DescriptiontaOS 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.
