CVE-2026-33286Network attack vector

Arbitrary method execution via unvalidated relationship names

Published Mar 23, 2026 · Updated Mar 23, 2026

Arbitrary method execution in Graphiti before 1.10.2 allows remote attackers to invoke public model methods through JSON:API writes. Graphiti::Util::ValidationResponse#all_valid? recursively passes unvalidated relationship names from the request to model.send(name). Exposure requires a create, update, or delete endpoint reachable by untrusted users; invoked methods can modify data or interrupt the application.
