Authenticated field disclosure via empty JSON Patch source
Published Jul 20, 2026 · Updated Jul 20, 2026
Incorrect authorization in SurrealDB before 3.1.0 allows remote authenticated users to read protected fields via JSON Patch operations. An empty from pointer in a copy or move operation makes UPDATE PATCH duplicate the entire target record into an attacker-chosen field, while filtering only the original protected names. Exploitation requires authenticated UPDATE PATCH access to a target record and discloses only fields in that record, without reported integrity or availability impact.
