CVE-2026-109340
SurrealDB from 3.1.0 before 3.3.0 contains an authorization bypass vulnerability that allows authenticated users to delete protected graph edges by triggering a REFERENCE ON DELETE CASCADE.
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
Description
SurrealDB from 3.1.0 before 3.3.0 contains an authorization bypass vulnerability that allows authenticated users to delete protected graph edges by triggering a REFERENCE ON DELETE CASCADE. Attackers with delete permission on a referenced table can delete a record whose cascade disables permission checks for edge cleanup, erasing edges despite the edge table's PERMISSIONS FOR delete clause.
