CVE-2026-111322

CriticalCVSS 9.8
Published: Translated: NVD NIST

Summary

Archon 0.2.13 through 0.11.1 contains a missing authentication vulnerability that allows unauthenticated attackers to access the /api/* control API, which binds to 0.0.0.0 by default. Attackers with network access can send messages to the AI coding agent, which runs with bypassPermissions, to execute commands on the host as the Archon user.

Risk Assessment

An attacker can execute arbitrary commands on the host, leading to full system compromise. Network access to the API is required.

Recommendation

Update Archon to a version later than 0.11.1. Restrict access to the control API via firewall or change the default binding to localhost.
