CVE-2026-111322 Details
Description
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.
A missing authentication vulnerability has been identified in Archon versions 0.2.13 through 0.11.1. The issue allows unauthenticated attackers to access the control API at /api/*, which is exposed by default. The API, intended for managing AI coding workflows, lacks authentication, leaving it open to exploitation by anyone with network access. This vulnerability could be particularly damaging, as it allows for unauthorized manipulation of the AI coding agent, including sending messages that the agent executes as commands on the host system.
To address this vulnerability, Archon should be configured to use a Postgres database and a valid BETTER_AUTH_SECRET, which enables the authentication gate. Additionally, the server should be bound to localhost by default to prevent external access.
