  "details": "A record user could read records the table\u0027s 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\u0027s 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 $value` passes for every record on the table \u2014 the subscriber receives notifications for records they should not see.\n\nRead-only impact, bounded to one table. Permission expressions that reference only field names, `$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.",
