Summary

taOS, a self-hosted AI agent OS, registers all system settings routes under a single APIRouter() with no admin authorization dependency before version 1.0.0-beta.25. Any authenticated user, including invited users with is_admin set to False, can read and overwrite the full system configuration and trigger a git pull, dependency reinstall and service restart. Exploiting the write endpoints corrupts configuration or causes denial of service for all users on the instance.

Mitigation

This issue has been patched in version 1.0.0-beta.25.
