  "details": "A `LIVE SELECT` subscription records the user\u0027s auth state (`$auth`, `$token`, `$session`, `$access`) when it is registered, and the server uses that recorded state to evaluate the table- and row-level `PERMISSIONS` clauses for every subsequent notification. The recorded state is never refreshed. \n\nWhen something changes the user\u0027s effective auth state \u2014 the originating session is invalidated, the session\u0027s TTL expires, or the user signs in, signs up, or authenticates as a different identity on the same connection \u2014 the subscription keeps delivering notifications under the old, stale auth state, and the `PERMISSIONS` that should now apply to the connection are never consulted.\n\n### Impact\n\nA user whose session has been revoked, expired, signed out of, or re-authenticated on the same connection continues to receive real-time notifications evaluated against the prior principal. The attacker does not gain access to new resources \u2014 only continued access to resources the prior principal was already permitted to read \u2014 but that continued access persists past the point the principal change should have ended it, and persists indefinitely until the originating connection is closed.\n\nThis is confidentiality-only: the dispatcher does not enable writes evaluated under the stranded principal.\n\n### Patches\n\n- **`invalidate()` and TTL expiry** \u2014 `RpcProtocol::invalidate` now calls `cleanup_lqs(session_id)` after clearing the session, dropping every LIVE owned by the now-invalidated session. The notification dispatcher additionally reads the originating session\u0027s `exp` and skips delivery once it has passed, closing the TTL-expiry leg without requiring the `Session` object to remain in memory.\n- **Principal change on `signin` / `signup` / `authenticate` / `refresh`** \u2014 each of these RPC methods now snapshots the session\u0027s auth principal (`Auth::id()` + `Auth::level()`) before mutating the session and, if the principal has changed after the operation, calls `cleanup_lqs(session_id)`. Token refresh against the same identity is therefore preserved; identity change tears stranded subscriptions down.\n\nVersions  3.1.0 and later are not affected by this issue.\n\n### Workarounds\n\nFor unpatched versions, clients should call `reset()` (which tears down all LIVE queries owned by the session) or `kill` each outstanding `live query ID` before signing out, signing in as a different identity, or signing up on an existing connection. There is no client-side workaround for the TTL-expiry leg; deployments concerned about it should restrict `DURATION FOR SESSION` on access methods that have permission to register LIVE queries.",
