Summary

NullHub through 2026.5.29 by nullclaw has missing authentication (CWE-306) that leaves the /api/* management API open. The auth_token field defaults to null and is never assigned, so the API accepts requests on non-loopback listeners. An unauthenticated attacker can control agents, rewrite configurations including provider credentials, and manage cron jobs and MCP servers.

Description from the CNA

NullHub through 2026.5.29 contains a missing authentication vulnerability that allows unauthenticated attackers to access the /api/* management API because the auth_token field defaults to null and is never assigned. Attackers sending requests without Authorization or Origin headers to non-loopback listeners can control agent instances, rewrite configurations including provider credentials, and manage cron jobs and MCP servers.
