CVE-2026-19010Public exploitNetwork attack vector

Unauthenticated agent execution via permission-bypassing message route

Published Aug 6, 2026 · Updated Aug 6, 2026

Missing authorization in TinyAGI 0.0.20 allows remote attackers to invoke agents through the Message API without authentication. The unauthenticated POST /api/message route queues attacker-controlled text, and processMessage sends it to Claude with --dangerously-skip-permissions. Network access to the API is sufficient; resulting tool actions are bounded by the files, commands, plugins, and internal resources available to the agent host.
