SurrealDB: LIVE query subscriptions survive session state changes, bypassing access controls
GitHub lists this reviewed advisory for surrealdb. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

source listed< 3.1.0
A `LIVE SELECT` subscription records the user's 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. When something changes the user's effective auth state — the originating session is invalidated, the session's TTL expires, or the user signs in, signs up, or authenticates as a different identity on the same connection — the subscription keeps delivering notifications under the old, stale auth state, and the `PERMISSIONS` that should now apply to the connection are never consulted. ### Impact A user whose session has been revoked, expired, signed out of, or re-authenticated on the same connection continues to receive real-time notifications evaluated against the prior principal.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 — only continued access to resources the prior principal was already permitted to read — but that continued access persists past the point the principal change should have ended it, and persists indefinitely until the originating connection is closed. This is
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.

- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
