  "title": "Permission bypass in SurrealDB reference delete actions",
  "summary": "SurrealDB versions with affected reference-on-delete handling can skip target-table permission checks during CASCADE, UNSET, or CUSTOM actions. An authenticated user allowed to delete a referenced record may thereby cause unauthorized changes, deletions, or configured expression execution on referencing records when the relevant reference action is configured.",
  "mitigation": "Upgrade the `surrealdb` package to version 4.0.0. Until upgrading, restrict delete permissions on referenced tables and avoid affected `REFERENCE ON DELETE` actions where practical.",
