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 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 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.
