Technical description

taOS is a self-hosted AI agent OS. Prior to version 1.0.0-beta.23, the POST /api/skill-exec/{skill_id}/call endpoint in taOS executes built-in skills — including the code_exec skill which runs arbitrary Python via subprocess.run(["python3", "-c", code]) — without performing any admin role check, skill ownership check, or agent assignment verification. Any authenticated non-admin user can supply attacker-controlled Python code in the request body and have it executed as the taOS backend process user on the host, achieving full remote code execution with no privilege escalation required beyond a valid (non-admin) session. This issue has been patched in version 1.0.0-beta.23.

———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.25.3h CVE-2026-675418.1 HIG

Prior to version 0.0.70, team-member management (add / remove / update) is gated only on team membership, not on the team creator/admin role — and TeamMember has no role column. Any non-creator member can seat an attacker account into the team; because credential team-shares are scoped only by TeamMember.user_id, the newly-added attacker can then decrypt every credential shared into that team (provider API keys, OAuth tokens.
