6.3 mediumEPSS 0.4%

Medium (6.3). EPSS 0.4% chance of exploitation in the next 30 days.

MaxKB is an open-source AI assistant for enterprise. Prior to version 2.10.6-lts, the ToolExecutor LD_PRELOAD 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.
