CVE Catalog

CVE-2026-110616

HighCVSS 8.1
Published: Translated: NVD NIST

Summary

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.

Risk Assessment

An unauthenticated attacker can take full control over agent instances and configuration, including provider credentials. This can result in compromise of the entire infrastructure managed by NullHub.

Recommendation

Update NullHub to a version later than 2026.5.29. Restrict API listening to the loopback interface only and enforce authentication.
