When the statement included a `SET id = edge:existing` clause, however, the new edge's id ended up pointing at an record that was already in storage. Rather than failing because the target already existed — which is what a create operation should do — the storage layer silently overwrote the existing edge. A caller with `CREATE` permission could therefore replace any existing edge on the table, even without `UPDATE` permission for that record.\n\n### Impact\n\nAn authenticated user with `CREATE` permission on an edge table could overwrite any existing record on that table — including edges they had no `UPDATE` permission for — by issuing a `RELATE` whose `SET id = …` resolved to the target record's id. The attack is integrity-only.\n\n### Patches\n\nA patch has been introduced that adds an explicit `Statement::Relate` arm using `put_record` instead of `set_record` when the create path is selected. Conflicting writes now return a `RecordExists` error.\n\n- Versions 3.1.0 and later are not affected by this issue.\n\nThis is a behaviour change for applications that relied on RELATE … SET id = … to silently replace existing edges; after the patch those calls return RecordExists instead. Applications that need \"create or replace\" semantics should use UPSERT (which is correctly permission-gated for the update half).\n\n### Workarounds\n\nThe defect only fires when the `RELATE` statement includes a `SET id = …` clause that resolves to an existing edge id. Applications that let SurrealDB auto-generate the edge id (the default — `RELATE a:1 -\u003e edge -\u003e b:1 SET \u003cdata\u003e` with no `id` override) are not affected, because auto-generated ids do not collide with existing records.\n\nWhere applications must use `SET id = …` (for example, to produce deterministic edge ids for idempotency), they should first verify that no record with the target id exists before issuing the statement, or restrict `CREATE` permission on the edge table to principals trusted with `UPDATE` on the same table.","status":"published","published":"2026-07-01T20:19:17Z","modified":"2026-07-01T20:19:18Z","cvss":[{"version":"3.1","score":4.3,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","level":"medium"}],"cwes":["CWE-285"],"updated_at":"2026-11-02T14:40:36.577366Z"},{"id":"GHSA-j8qv-6jr5-7pcx","title":"SurrealDB before 3.1.0 contains an authorization bypass vulnerability in the RELATE statement...","description":"SurrealDB before 3.1.0 contains an authorization bypass vulnerability in the RELATE statement that allows authenticated users with CREATE permission to overwrite existing edge records without UPDATE permission.
