Dify before version 1.14.0 contains an authorization bypass vulnerability that allows authenticated users to read the full contents of files uploaded by other users within the same tenant by supplying an arbitrary file UUID in the files array of a chat-messages request. Attackers can exploit insufficient permission verification in the chat-messages endpoints to access files without ownership validation, bypassing workspace separation and signed URL protections to retrieve sensitive file contents through workflow processing.

Dify is an open-source LLM app development platform. Prior to version 1.13.1, using the method POST /api/files/upload, any unauthenticated user can upload an SVG file with XSS. The method POST /v1/files/upload, which requires authentication through the application API, is also vulnerable. This issue has been patched in version 1.13.1.

A Cross-Origin Resource Sharing (CORS) misconfiguration vulnerability exists in Dify v1.9.1 in the /console/api/system-features endpoint. The endpoint implements an overly permissive CORS policy that reflects arbitrary Origin headers and sets Access-Control-Allow-Credentials: true, allowing any external domain to make authenticated cross-origin requests. NOTE: the Supplier disputes this, providing the rationale of "sending requests with credentials does not provide any additional access compared to unauthenticated requests."

A Cross-Origin Resource Sharing (CORS) misconfiguration vulnerability exists in Dify v1.9.1 in the /console/api/setup endpoint. The endpoint implements an insecure CORS policy that reflects any Origin header and enables Access-Control-Allow-Credentials: true, permitting arbitrary external domains to make authenticated requests. NOTE: the Supplier disputes this because the endpoint configuration is intentional to support bootstrap.

Dify v1.9.1 is vulnerable to Insecure Permissions. An unauthenticated attacker can directly send HTTP GET requests to the /console/api/system-features endpoint without any authentication credentials or session tokens. The endpoint fails to implement proper authorization checks, allowing anonymous access to sensitive system configuration data. NOTE: The maintainer states that the endpoint is unauthenticated by design and serves as a bootstrap mechanism required for the dashboard initialization. They also state that the description inaccurately classifies the returned data as sensitive system configuration, stating that the data is non-sensitive and required for client-side rendering. No PII, credentials, or secrets are exposed.

Default credentials in Dify thru 1.5.1. PostgreSQL username and password specified in the docker-compose.yaml file included in its source code. NOTE: the Supplier reports that the Docker configuration does not make PostgreSQL (on TCP port 5432) exposed by default in version 1.0.1 or later.

In langgenius/dify-web version 1.6.0, the authentication mechanism reveals the existence of user accounts by returning different error messages for non-existent and existing accounts. Specifically, when a login or registration attempt is made with a non-existent username or email, the system responds with a message such as "account not found." Conversely, when the username or email exists but the password is incorrect, a different error message is returned. This discrepancy allows an attacker to enumerate valid user accounts by analyzing the error responses, potentially facilitating targeted social engineering, brute force, or credential stuffing attacks.

Dify is an LLM application development platform. In Dify versions through 1.9.1, the MCP OAuth component is vulnerable to cross-site scripting when a victim connects to an attacker-controlled remote MCP server. The vulnerability exists in the OAuth flow implementation where the authorizationurl provided by a remote MCP server is directly passed to window.open without validation or sanitization. An attacker can craft a malicious MCP server that returns a JavaScript URI (such as javascript:alert(1)) in the authorizationurl field, which is then executed when the victim attempts to connect to the MCP server. This allows the attacker to execute arbitrary JavaScript in the context of the Dify application.

Dify is an open-source LLM app development platform. In version 1.8.1, a broken access control vulnerability on the /console/api/apps/<APPID>chat-messages?conversationid=<CONVERSATIONID>&limit=10 endpoint allows users in the same workspace to read chat messages of other users. A regular user is able to read the query data and the filename of the admins and probably other users chats, if they know the conversationid. This impacts the confidentiality of chats. This issue has been patched in version 1.9.0.

An XSS vulnerability exists in langgenius/dify versions prior to 1.1.3, specifically affecting Firefox browsers. This vulnerability allows an attacker to obtain the administrator's token by sending a payload in the published chat. When the administrator views the conversation content through the monitoring/log function using Firefox, the XSS vulnerability is triggered, potentially exposing sensitive token information to the attacker.

langgenius/dify versions 1.1.0 to 1.1.2 are vulnerable to unsanitized input in the code node, allowing execution of arbitrary code with full root permissions. The vulnerability arises from the ability to override global functions in JavaScript, such as parseInt, before sandbox security restrictions are imposed. This can lead to unauthorized access to secret keys, internal network servers, and lateral movement within dify.ai. The issue is resolved in version 1.1.3.

Dify is an open-source LLM app development platform. In version 1.2.0, there is insufficient filtering of user input by web applications. Attackers can use website vulnerabilities to inject malicious script code into web pages. This may result in a cross-site scripting (XSS) attack when a user browses these web pages. At time of posting, there is no known patched version.

DIFY is an open-source LLM app development platform. Prior to version 1.3.0, a clickjacking vulnerability was found in the default setup of the DIFY application, allowing malicious actors to trick users into clicking on elements of the web page without their knowledge or consent. This can lead to unauthorized actions being performed, potentially compromising the security and privacy of users. This issue has been fixed in version 1.3.0.

Dify is an open-source LLM app development platform. Prior to version 0.6.12, a normal user is able to access and modify APP orchestration, even though the web UI of APP orchestration is not presented for a normal user. This access control flaw allows non-admin users to make unauthorized access and changes on the APPSs. This issue has been patched in version 0.6.12. A workaround for this vulnerability involves updating the the access control mechanisms to enforce stricter user role permissions and implementing role-based access controls (RBAC) to ensure that only users with admin privileges can access Orchestration of the APPs.

Dify is an open-source LLM app development platform. Prior to version 0.6.12, a vulnerability was identified in the DIFY where normal users can enable or disable apps through the API, even though the web UI button for this action is disabled and normal users are not permitted to make such changes. This access control flaw allows non-admin users to make unauthorized changes, which can disrupt the functionality and availability of the APPS. This issue has been patched in version 0.6.12. A workaround for this vulnerability involves updating the API access control mechanisms to enforce stricter user role permissions and implementing role-based access controls (RBAC) to ensure that only users with admin privileges can send enable or disable requests for apps.

Dify is an open-source LLM app development platform. Prior to version 0.6.12, a vulnerability was identified in the DIFY where normal users are improperly granted permissions to edit APP names, descriptions and icons. This access control flaw allows non-admin users to modify app details, despite being restricted from viewing apps, which poses a security risk to the integrity of the application. This issue has been patched in version 0.6.12. A workaround for this vulnerability involves updating the access control mechanisms to enforce stricter user role permissions and implementing role-based access controls (RBAC) to ensure that only users with admin privileges can modify app details.

Dify is an open-source LLM app development platform. In versions 0.6.8 and prior, a vulnerability was identified in the DIFY AI where normal users are improperly granted permissions to export APP DSL. The feature in '/export' should only allow administrator users to export DSL. A workaround for this vulnerability involves updating the access control mechanisms to enforce stricter user role permissions and implementing role-based access controls (RBAC) to ensure that only users with admin privileges can export the APP DSL. This vulnerability is fixed in 0.6.13.

Dify v1.0 was discovered to contain a Server-Side Request Forgery (SSRF) via the component controllers.console.remotefiles.RemoteFileUploadApi.

A Server-Side Request Forgery (SSRF) vulnerability was identified in langgenius/dify version 0.10.2. The vulnerability occurs in the 'Create Knowledge' section when uploading DOCX files. If an external relationship exists in the DOCX file, the reltype value is requested as a URL using the 'requests' module instead of the 'ssrfproxy', leading to an SSRF vulnerability. This issue was fixed in version 0.11.0.

A stored cross-site scripting (XSS) vulnerability exists in the latest version of langgenius/dify. The vulnerability is due to improper validation and sanitization of user input in SVG markdown support within the chatbot feature. An attacker can exploit this vulnerability by injecting malicious SVG content, which can execute arbitrary JavaScript code when viewed by an admin, potentially leading to credential theft.

In langgenius/dify v0.10.1, the /forgot-password/resets endpoint does not verify the password reset code, allowing an attacker to reset the password of any user, including administrators. This vulnerability can lead to a complete compromise of the application.

A vulnerability in langgenius/dify versions <=v0.9.1 allows for code injection via internal SSRF requests in the Dify sandbox service. This vulnerability enables an attacker to execute arbitrary Python code with root privileges within the sandbox environment, potentially leading to the deletion of the entire sandbox service and causing irreversible damage.

langgenius/dify version v0.10.1 contains a vulnerability where there are no limits applied to the number of code guess attempts for password reset. This allows an unauthenticated attacker to reset owner, admin, or other user passwords within a few hours by guessing the six-digit code, resulting in a complete compromise of the application.

langgenius/dify version 0.10.1 contains a Server-Side Request Forgery (SSRF) vulnerability in the test functionality for the Create Custom Tool option via the REST API POST /console/api/workspaces/current/tool-provider/api/test/pre. Attackers can set the url in the servers dictionary in OpenAI's schema with arbitrary URL targets, allowing them to abuse the victim server's credentials to access unauthorized web resources.

langgenius/dify version 0.9.1 contains a Server-Side Request Forgery (SSRF) vulnerability. The vulnerability exists due to improper handling of the apiendpoint parameter, allowing an attacker to make direct requests to internal network services. This can lead to unauthorized access to internal servers and potentially expose sensitive information, including access to the AWS metadata endpoint.
