taOS is a self-hosted AI agent OS. Prior to version 1.0.0-beta.25, tinyagentos (taOS) registers all system settings routes under a single APIRouter() instance created with no admin authorization dependency. Any authenticated user—including non-admin invited users whose is_admin flag is explicitly False—can read the full system configuration, overwrite it, modify platform settings, trigger a git pull + dependency reinstall + service restart, and switch the tracked update branch. Successful exploitation of the write endpoints causes immediate configuration corruption or a denial of service for all users on the instance from a low-privileged account. This issue has been patched in version 1.0.0-beta.25.
