{"id":"GHSA-6wqw-vhfr-9999","aliases":[],"url":"https://o3.security/vulnerability/GHSA-6wqw-vhfr-9999","summary":"SurrealDB: Authenticated subscribers can read records hidden by SELECT permissions via LIVE subscriptions","details":"A record user could read records the table's SELECT permission expression should have hidden, when that expression referenced `$value`, `$before`, `$after`, or `$event`. Binding a chosen value to that name before registering a `LIVE SELECT` caused notifications to evaluate the permission against the attacker's input instead of the real document.\n\n### Impact\n\nA record user binds a value to `$value`, `$before`, `$after`, or `$event` (e.g. `LET $value = [$auth.id]`) and registers `LIVE SELECT * FROM person`. The captured value shadows the real document at notification time, so a SELECT permission like `WHERE $auth.id.id() IN $value` passes for every record on the table — the subscriber receives notifications for records they should not see.\n\nRead-only impact, bounded to one table. Permission expressions that reference only field names, `$auth`, or `$session` are unaffected.\n\n### Patches\n\nA patch has been introduced that re-orders the LIVE notification parameter binding so captured user variables are added first and the trusted document-context and session parameters are added last.\n\n- Versions 3.1.0 and later are not affected by this issue.\n\n### Workarounds\n\nAffected users who are unable to update should avoid table-`PERMISSIONS` and LIVE `WHERE` expressions that read user-named variables (`$value`, `$before`, `$after`, `$event`) without also gating on a system-derived field such as the record id.","published":"2026-07-01T20:20:00Z","modified":"2026-07-01T20:30:08.840694225Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"surrealdb","fixedVersion":"3.1.0"}],"fix":{"url":"https://github.com/surrealdb/surrealdb/commit/6bcc55c9c0494a0d4d36821019b54459f7162af7","label":"surrealdb/surrealdb@6bcc55c"},"references":[{"type":"WEB","url":"https://github.com/surrealdb/surrealdb/security/advisories/GHSA-6wqw-vhfr-9999"},{"type":"WEB","url":"https://github.com/surrealdb/surrealdb/commit/6bcc55c9c0494a0d4d36821019b54459f7162af7"},{"type":"WEB","url":"https://github.com/orgs/surrealdb/discussions/101"},{"type":"PACKAGE","url":"https://github.com/surrealdb/surrealdb"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-01T20:30:08.840694225Z"}}
