MaxKB is an open-source AI assistant for enterprise. Prior to version 2.10.6-lts, the ToolExecutor LDPRELOAD sandbox hooks execve, execvpe, and execveat to prevent subprocess creation but does not hook fexecve. An authenticated attacker able to execute tool code can call fexecve to start a process outside the sandbox's intended subprocess policy. This issue is fixed in version 2.10.6-lts.

MaxKB is an open-source AI assistant for enterprise. In version 2.10.3-lts and earlier, the knowledge web-document import and synchronization crawler passes an authenticated workspace user's URL to Fork.fork, which calls requests.get with verify=False and without restricting schemes, loopback, link-local, private, or reserved addresses. The response body is converted into imported document content, allowing a low-privileged user to read cloud metadata or internal HTTP services through the MaxKB server. No fixed version is available as of this review.

MaxKB is an open-source AI assistant for enterprise. Prior to 2.10.5-lts, authenticated workspace members can inject control characters into AWS Bedrock accesskeyid and secretaccesskey fields that updateawscredentials writes to /root/.aws/credentials without safe parsing. An attacker can append a new AWS profile containing credentialprocess, then select that profile during a later model-validation request so botocore executes an attacker-controlled command as root. This vulnerability is fixed in 2.10.5-lts.

MaxKB is an open-source AI assistant for enterprise. In 2.7.0 through 2.10.4-lts, POST /chat/api/{applicationid}/chat/{chatid}/sharechat verifies that a conversation exists but does not verify that it belongs to the authenticated chatuserid or to the application bound to the caller's token. An attacker with any chat token and a known victim chatid can create an unauthenticated public ChatShareLink exposing the victim's conversation and can create PublicFileAccess state that makes associated files retrievable without credentials, with no available revoke path. No fixed version is available as of this review.

MaxKB is an open-source AI assistant for enterprise. In version 2.10.3-lts and earlier, the model parameter form route authorizes the path workspace but ModelSerializer.ModelParams loads and saves a Model by id alone without including workspaceid in the query. An authenticated user with model read permission in an attacker-controlled workspace can supply a known victim modelid to read or overwrite the victim's modelparamsform in another workspace, potentially altering workflows that use those defaults. No fixed version is available as of this review.

MaxKB is an open-source AI assistant for enterprise. Prior to version 2.10.5-lts, assistants with a tool, MCP tool, skill, or sub-application use SandboxShellBackend, which exposes an execute shell tool without excluding it and omits execute from interrupton, so human approval is not required. Untrusted chat or ingested content can therefore cause command execution; source deployments with MAXKBSANDBOX disabled run commands directly as the application user, while the official root container's string-based gosu wrapper allowed shell metacharacters to execute outside the intended sandbox. This issue is fixed in version 2.10.5-lts.

MaxKB before 2.10.0 contains a server-side request forgery vulnerability in tool creation and update endpoints that allows authenticated users to make arbitrary server requests by supplying unvalidated downloadCallbackUrl and downloadurl parameters. Attackers with default workspace USER role can exploit this to access internal network services by providing malicious URLs to the ToolSerializer endpoints.

MaxKB is an open-source AI assistant for enterprise. Prior to 2.10.0-lts, MaxKB tool import functionality in apps/tools/serializers/tool.py and MCP referencing mode in apps/application/chatpipeline/step/chatstep/impl/basechatstep.py do not consistently validate MCP transport type, allowing an authenticated user to import a .tool file containing stdio transport with malicious commands and trigger the configuration through an AI Chat node so MultiServerMCPClient executes arbitrary system commands. This issue is fixed in version 2.10.0-lts.

MaxKB is an open-source AI assistant for enterprise. Prior to version 1.10.8-lts, Sandbox only restricts the execution permissions of binary files in common directories, such as /bin,/usr/bin, etc. Therefore, attackers can exploit some files with execution permissions in non blacklisted directories to carry out attacks. Version 1.10.8-lts fixes the issue.

A vulnerability was found in 1Panel-dev MaxKB up to 1.10.7. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the component Knowledge Base Module. The manipulation leads to csv injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 1.10.8 is able to address this issue. It is recommended to upgrade the affected component. The vendor was contacted early about this disclosure.
