Source: NVD(opens in a new tab)
Identifier: CVE-2026-67547
Published: November 11, 2026
Record updated: November 12, 2026

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.
EPSS: 0.8%

Summary

taOS, a self-hosted AI agent OS, prior to 1.0.0-beta.23 exposes POST /api/skill-exec/{skill_id}/call, which runs built-in skills without any admin role, skill ownership, or agent assignment check. Any authenticated non-admin user can submit Python code in the request body, and the code_exec skill runs it via subprocess.run(["python3", "-c", code]) as the taOS backend process user, giving full remote code execution on the host.

Mitigation

Fixed in 1.0.0-beta.23.
