CVE-2025-15550Public exploitNetwork attack vectorHinoki check available

Unauthorized GraphQL actions via GET-based CSRF

Published Jan 29, 2026 · Updated Jan 29, 2026

Cross-site request forgery in Birkir Gudjonsson Prime 0 through 0.4.0.beta.0 allows attackers to submit GraphQL actions via GET. The /graphql endpoint processes query parameters on GET requests without verifying that the privileged user intended the request. Exploitation requires an active privileged user to load attacker-controlled content, and the documented consequence is unauthorized actions under that user's authority.
