SECURITY-3792 / CVE-2026-57280 Script Security Plugin provides a sandbox feature that allows running user-provided scripts safely by intercepting and checking potentially unsafe operations.
Script Security Plugin 1402.v94c9ce464861 and earlier does not intercept the implicit type cast applied to each element of the iterated collection in a typed for loop (e.g. for (Type t in collection)), as this cast is performed during bytecode generation rather than in the transformed script AST.
This allows attackers able to provide sandboxed scripts to invoke constructors of arbitrary types without those invocations being checked by the sandbox, bypassing the sandbox protection. This can be used to execute arbitrary code on the Jenkins controller.
SECURITY-3793 / CVE-2026-57281 Script Security Plugin 1402.v94c9ce464861 and earlier does not reject Groovy AST transformation annotations such as @CompileStatic and @TypeChecked that carry an extensions member, which causes Groovy to load and execute a script from the classpath at compile time, before the sandbox is applied.
This may allow attackers able to define and run sandboxed scripts to execute code outside the sandbox, in the rare case that a suitable Groovy script is present on the classpath of the component that evaluates the script.
NOTE: The Jenkins security team has been unable to identify any Groovy source files in Jenkins core or plugins that would allow attackers to execute dangerous code. While the severity of this issue is declared as High due to the potential impact, successful exploitation is considered very unlikely.
SECURITY-3723 / CVE-2026-57282 Git client Plugin 6.6.0 and earlier does not correctly escape the workspace directory name when it is embedded into the SSH wrapper script generated by the "Manually provided keys" Git Host Key Verification strategy on Unix agents.
This allows attackers able to control the name of a build's working directory (e.g. through a build parameter that determines the workspace directory) to inject shell command substitution and execute arbitrary commands on the agent.
NOTE: This vulnerability only has an impact when attackers can control working directories (e.g., the argument to the dir(…) Pipeline step) while not being able to control the Pipeline itself or the programs or build scripts it executes.
NOTE: This vulnerability has been reported through the Jenkins Bug Bounty Program sponsored by the European Commission.
SECURITY-3677 / CVE-2026-57283 (CSRF) & CVE-2026-57284 (unrestricted instantiation of types) Pipeline: Groovy Plugin 4331.v9d06ed4658ff and earlier does not restrict the types that can be instantiated through the Pipeline Snippet Generator, instantiating any type with a constructor annotated with @DataBoundConstructor in response to a request.
This allows attackers to have Pipeline: Groovy Plugin instantiate types related to job or system configuration other than Pipeline steps.
Additionally, this HTTP endpoint can be accessed using the GET method and does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability. This allows attackers to create a script approval request attributed to another user, impersonating a trusted user when social engineering an administrator into approving a malicious script.
NOTE: This vulnerability has been reported through the Jenkins Bug Bounty Program sponsored by the European Commission.
SECURITY-3808 / CVE-2026-57285 GitHub Branch Source Plugin 1967.1969.v205fd594c821 and earlier does not perform a permission check in an HTTP endpoint that lists the GitHub API endpoints configured in the global plugin configuration.
This allows attackers with Overall/Read permission to obtain the URLs of GitHub Enterprise servers configured by administrators.
NOTE: This vulnerability has been reported through the Jenkins Bug Bounty Program sponsored by the European Commission.
SECURITY-3745 / CVE-2026-57286 Git Parameter Plugin 462.vdcf3df2ed2ca and earlier does not perform a permission check in an HTTP endpoint that populates the list of values for Git parameters by querying the SCM configured on a job, using the SCM credentials configured in Jenkins.
This allows attackers with Item/Read permission to obtain information about the SCM repository used by a job they would otherwise be unable to access, such as branch names, tag names, and revision metadata.
SECURITY-3742 / CVE-2026-57287 Job Configuration History Plugin 1356.ve360da6c523a and earlier does not redact the encrypted values of secrets when displaying historical job and agent configurations through its "View as XML" / "(RAW)" feature and its configuration diff views.
This allows attackers with Item/Extended Read permission (but not Item/Configure permission) to view the encrypted values of secrets, such as build trigger tokens, that Jenkins would otherwise redact from the configuration shown to them.
SECURITY-3651 / CVE-2026-57288 In Active Directory Plugin 2.41.1 and earlier, the Windows native (ADSI) authentication path does not escape the user name before building the LDAP search filter.
This allows unauthenticated attackers to inject LDAP wildcard characters into the user name, enabling them to enumerate directory user and group names, and to authenticate as a matching user when they know that user's password but not their exact user name.
SECURITY-3759 / CVE-2026-57300 MCP Server Plugin 0.177.v629fdb2557fe and earlier does not perform a permission check in the getReplayScripts MCP tool that returns the replay script of a Pipeline build.
This allows attackers with Item/Read permission to obtain the Pipeline script of jobs.
SECURITY-3856 / CVE-2026-57289 Bitbucket Push and Pull Request Plugin 3.3.8 and earlier unconditionally disables SSL/TLS certificate and hostname validation for the connections it makes to Bitbucket Server using Bearer token authentication.
Because the Bearer token is transmitted in these requests, this allows attackers able to intercept network traffic to capture the token and impersonate the Jenkins controller to Bitbucket Server.
SECURITY-3769 / CVE-2026-57290 Priority Sorter Plugin 936.v2c01c6b84449 and earlier does not require POST requests in an HTTP endpoint that saves the global job priority configuration.
This allows attackers to overwrite the global job priority configuration.
SECURITY-3762 (1) / CVE-2026-57291 (missing permission check) & CVE-2026-57292 (CSRF) Gitee Plugin 1288.v18bdebc9069b and earlier does not perform permission checks in several HTTP endpoints implementing form validation for its global configuration.
This allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.
Additionally, these HTTP endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
SECURITY-3762 (2) / CVE-2026-57293 Gitee Plugin 1288.v18bdebc9069b and earlier does not correctly perform a permission check in an HTTP endpoint.
This allows attackers with global Item/Configure permission (while lacking Item/Configure permission on any particular job) to enumerate credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability.
SECURITY-3774 / CVE-2026-57294 (missing permission check) & CVE-2026-57295 (CSRF) EC2 Fleet Plugin 4.2.3.539.v8fedff2a81c3 and earlier does not perform permission checks in several HTTP endpoints used to validate cloud configurations.
This allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing AWS credentials stored in Jenkins.
Additionally, these HTTP endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
SECURITY-3777 / CVE-2026-57296 External Workspace Manager Plugin 1.3.2 and earlier does not reject .. path segments when validating the custom workspace path provided to the exwsAllocate Pipeline step, allowing the resulting workspace path to escape the configured disk mount point.
This allows attackers with Item/Configure permission to read arbitrary files on the Jenkins controller file system, which can lead to remote code execution.
SECURITY-3697 (1) / CVE-2026-57297 (missing permission check) & CVE-2026-57298 (CSRF) Contrast Continuous Application Security Plugin 3.11 and earlier does not perform a permission check in an HTTP endpoint that tests the connection to a Contrast TeamServer.
This allows attackers with Overall/Read permission to connect to an attacker-specified URL using an attacker-specified username, API key, and service key.
Additionally, this HTTP endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
SECURITY-3697 (2) / CVE-2026-57299 Contrast Continuous Application Security Plugin 3.11 and earlier does not perform permission checks in several HTTP endpoints that fill list box options with the names of the configured Contrast metadata.
This allows attackers with Overall/Read permission to enumerate the names of configured Contrast metadata.
SECURITY-3649 / CVE-2026-57301 OWASP ZAP Plugin 1.0.7 and earlier does not support distributed builds, causing the file operations and build process of its "Automatically build ZAP" feature to be performed on the Jenkins controller rather than on the agent the build is assigned to.
This allows attackers with Item/Configure permission to configure the feature to build an attacker-controlled project, executing arbitrary code on the Jenkins controller and bypassing any restriction confining the build to a specific agent.
As of publication of this advisory, there is no fix.
SECURITY-3555 / CVE-2026-57302 FitNesse Plugin 1.36 and earlier stores passwords unencrypted in job config.xml files on the Jenkins controller as part of its configuration.
These passwords can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.
As of publication of this advisory, there is no fix.
SECURITY-3692 (1) / CVE-2026-57303 Assembla Plugin 1.4 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks when parsing responses from the configured Assembla server.
This allows attackers able to control the responses of the configured Assembla server to extract secrets from the Jenkins controller or perform server-side request forgery.
As of publication of this advisory, there is no fix.
SECURITY-3692 (2) / CVE-2026-57304 (missing permission check) & CVE-2026-57305 (CSRF) Assembla Plugin 1.4 and earlier does not perform a permission check in an HTTP endpoint that tests the connection to an Assembla server.
This allows attackers with Overall/Read permission to connect to an attacker-specified URL using an attacker-specified username and password.
Additionally, this HTTP endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
NOTE: This does not allow exploiting the XML external entity (XXE) vulnerability described in the previous advisory entry.
As of publication of this advisory, there is no fix.
SECURITY-3747 / CVE-2026-57306 (CSRF) & CVE-2026-57307 (missing permission check) Zowe zDevOps Plugin 1.1.3.50.ve350c9b450b1 and earlier does not perform a permission check in an HTTP endpoint implementing a connection test.
This allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.
Additionally, this HTTP endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
As of publication of this advisory, there is no fix.

SECURITY-3929 / CVE-2026-92122 Script Security Plugin provides a sandbox feature that allows running user-provided scripts safely by intercepting and checking potentially unsafe operations.
Groovy coerces a value to an interface by creating a proxy that forwards each interface method call to a method of the same name on that value.
Script Security Plugin 1415.v9af9b3ac253d and earlier does not check the method that the proxy calls when the value inherits a method of the same name as an interface method.
This allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.
SECURITY-3931 / CVE-2026-92123 Script Security Plugin provides a sandbox feature that allows running user-provided scripts safely by intercepting and checking potentially unsafe operations.
Script Security Plugin 1415.v9af9b3ac253d and earlier does not intercept operations performed on a null receiver (method calls, property and attribute accesses, and array accesses).
This allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.
SECURITY-3923 / CVE-2026-92124 Script Security Plugin provides a sandbox feature that allows running user-provided scripts safely by intercepting and checking potentially unsafe operations.
Groovy casts a collection to another type using the elements of that collection, either passing them to a constructor of that type or casting each of them.
Script Security Plugin 1415.v9af9b3ac253d and earlier checks the operations Groovy will perform with the elements it reads from the collection, but performs the cast on the collection itself rather than on the elements it checked.
This allows attackers with permission to define and run sandboxed scripts, including Pipelines, to have the cast performed on different elements by overriding the methods of a collection, bypassing the sandbox protection and executing arbitrary code in the context of the Jenkins controller JVM.
SECURITY-3925 (1) / CVE-2026-92125 Script Security Plugin provides a sandbox feature that allows running user-provided scripts safely by intercepting and checking potentially unsafe operations.
Script Security Plugin 1415.v9af9b3ac253d and earlier does not reject the @GroovyASTTransformationClass annotation, which a script can use to link an annotation type it declares to an arbitrary AST transformation, causing Groovy to run that transformation at compile time, before the sandbox is applied.
This allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.
SECURITY-3925 (2) / CVE-2026-92126 Script Security Plugin provides a sandbox feature that allows running user-provided scripts safely by intercepting and checking potentially unsafe operations.
Groovy's @Builder annotation generates builder code at compile time using the strategy class named by its builderStrategy member, which can be one of the strategies provided by Groovy or a custom implementation.
Script Security Plugin 1415.v9af9b3ac253d and earlier does not reject @Builder annotations whose builderStrategy member names an arbitrary class, which causes Groovy to instantiate that class at compile time, before the sandbox is applied.
This may allow attackers with permission to define and run sandboxed scripts, including Pipelines, to execute code outside the sandbox, in the rare case that a suitable class is present on the classpath of the component that evaluates the script.
SECURITY-3897 / CVE-2026-92127 Script Security Plugin allows Groovy scripts to load classpath entries from JAR files, which administrators must approve before any script is allowed to use them.
Script Security Plugin 1415.v9af9b3ac253d and earlier automatically approves the classpath entries in an item configuration when a user with Overall/Administer permission copies the item, or updates that configuration through the REST API or CLI, allowing attackers able to define classpath entries to execute arbitrary code in the context of the Jenkins controller JVM.
SECURITY-3932 / CVE-2026-92128 Script Security Plugin allows Groovy scripts to load classpath entries from JAR files, specified either by file path or by URL, which administrators must approve before any script is allowed to use them.
Script Security Plugin 1415.v9af9b3ac253d and earlier downloads a JAR file specified by URL twice when a script is evaluated, confirming the approval of the first download and loading the classpath entries from the second.
This results in a time-of-check to time-of-use (TOCTOU) race condition that allows attackers able to define classpath entries to execute arbitrary code in the context of the Jenkins controller JVM.
NOTE: Exploitation requires an already approved JAR file to be served from an attacker-controlled server.
SECURITY-3977 / CVE-2026-92129 Script Security Plugin provides a sandbox feature that allows running user-provided scripts safely by intercepting and checking potentially unsafe operations.
Groovy allows an existing class to be extended at runtime with additional methods.
Script Security Plugin 1415.v9af9b3ac253d and earlier does not check calls to such methods from sandboxed scripts.
This allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute code outside the sandbox.
NOTE: Exploitation requires that the dynamically added methods have already been defined by code running outside the sandbox, e.g. by a plugin, as sandboxed scripts cannot extend a class themselves.
SECURITY-3729 / CVE-2026-92130 Pipeline: Multibranch Plugin 841.vec5b9e1806ec and earlier does not set the appropriate context for credentials lookup in the resolveScm Pipeline step, allowing the use of System-scoped credentials otherwise reserved for the global configuration.
This allows attackers with Item/Configure permission to access and capture credentials they are not entitled to use.
SECURITY-3796 / CVE-2026-92131 Pipeline: Groovy Libraries Plugin provides the library step to retrieve a shared library from an SCM, using a library path to specify the directory containing the library inside the SCM checkout.
Pipeline: Groovy Libraries Plugin 805.vafc79344957d and earlier does not restrict that library path to a relative path inside the SCM checkout.
Additionally, it follows symbolic links to locations outside of the SCM checkout when retrieving the library.
This results in a path traversal vulnerability, allowing attackers able to configure Pipelines to read files in a resources directory and to delete files in a test directory on the Jenkins controller file system.
SECURITY-4028 / CVE-2026-92132 Gradle Plugin provides global options for administrators to detect build scan links in build logs, and to show an enriched build scan summary for those build scans on the build page.
In Gradle Plugin 2.19.1252.v15196b5a6e10 and earlier, the enriched build scan summary requests data from the build scan link detected in the build log, even when a Develocity server URL is configured in the global configuration.
This allows attackers able to control the build log to capture the Develocity access key configured in the global configuration by having Jenkins connect to an attacker-specified URL.
SECURITY-3851 / CVE-2026-92133 GitLab Plugin allows jobs to override the globally configured GitLab API token credentials with an alternative one, and caches the GitLab API client it builds for those credentials.
GitLab Plugin 1.2149.vcfc32c82bf7f and earlier derives the cache key from the credentials ID alone, omitting the folder in which the credentials are resolved, resulting in the GitLab API token credentials being taken from the folder of the job that created the cache entry.
This allows attackers with Item/Configure permission to access GitLab API token credentials they are not entitled to use.
SECURITY-3937 / CVE-2026-92134 Warnings Plugin uses analysis results IDs to create the links to analysis results on the Jenkins UI.
Warnings Plugin 13.10258.va17d49a78c3b and earlier does not validate the analysis results ID when a job configuration is submitted through the REST API. This allows attackers with Item/Configure permission to use a javascript: scheme URL as identifier, resulting in a stored cross-site scripting (XSS) vulnerability.
TIP: On Jenkins 2.539 and newer, LTS 2.541.1 and newer, enforcing Content Security Policy protection mitigates this vulnerability.
SECURITY-4118 / CVE-2026-92135 Coverage Plugin uses coverage results IDs to create the links to coverage results on the Jenkins UI.
Coverage Plugin 3.3358.v9487dde48783 and earlier does not validate the coverage results ID when a job configuration is submitted through the REST API. This allows attackers with Item/Configure permission to use a javascript: scheme URL as identifier, resulting in a stored cross-site scripting (XSS) vulnerability.
TIP: On Jenkins 2.539 and newer, LTS 2.541.1 and newer, enforcing Content Security Policy protection mitigates this vulnerability.
SECURITY-3992 / CVE-2026-92136 OWASP Dependency-Check Plugin 5.6.4 and earlier does not escape CWE values from Dependency-Check reports on the Jenkins UI.
This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.
TIP: On Jenkins 2.539 and newer, LTS 2.541.1 and newer, enforcing Content Security Policy protection mitigates this vulnerability.
SECURITY-3971 / CVE-2026-92137 Robot Framework Plugin 6.2.2 and earlier does not check that the archive directory configured for Robot Framework report files is contained within the build directory on the Jenkins controller.
This allows attackers with Item/Configure permission to create or replace arbitrary files on the Jenkins controller file system with attacker-specified content, which can lead to remote code execution.
SECURITY-3778 / CVE-2026-92138 Bitbucket Server Integration Plugin implements an OAuth provider for Bitbucket Server.
The OAuth authorization endpoint in Bitbucket Server Integration Plugin 6.0.1 and earlier reads the oauthcallback URL from the submitted form rather than from the server-side stored request token. An attacker who can manipulate the form submission can cause Jenkins to redirect the authorizing user's browser to an arbitrary URL. The redirect includes the oauthtoken and oauthverifier parameters, allowing the attacker to complete the OAuth flow and obtain an access token on behalf of the victim.
NOTE: Exploiting this vulnerability requires the attacker to have previously registered an OAuth consumer (requires Overall/Administer permission) and to be able to intercept and modify the victim's form submission.
SECURITY-3980 / CVE-2026-92139 Bitbucket Push and Pull Request Plugin provides a webhook endpoint at /bitbucket-hook/ to receive webhook notifications.
When acting on these notifications, Bitbucket Push and Pull Request Plugin 4.0.1 and earlier trusts values provided in the webhook payload, including certain URLs, and uses configured Bitbucket credentials to connect to those URLs.
This allows attackers to capture Bitbucket credentials stored in Jenkins by sending a crafted webhook payload.
SECURITY-4027 / CVE-2026-92140 Gitee Plugin 1301.v8957053c7902 and earlier does not escape the sender name from Gitee push webhook payloads in build causes.
This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to trigger builds via the Gitee Plugin webhook endpoint.
SECURITY-3767 / CVE-2026-92141 Keycloak Authentication Plugin 2.4.1 and earlier does not restrict the redirect URL after login.
This allows attackers to perform phishing attacks by having users go to a Jenkins URL that will forward them to a different site after successful authentication.
