SurrealDB: Custom API route lets authenticated callers override namespace/database scope via URL path
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< 3.2.0
An authenticated user scoped to one namespace/database could invoke a custom API (`DEFINE API`) belonging to a different namespace/database, reaching another tenant's endpoint. The route `/api/{namespace}/{database}/{endpoint}` took the namespace and database from the URL and applied them to the caller's session before the endpoint was looked up or run, without checking that the caller's authenticated scope covered them. Because a custom API handler runs with permissions disabled (definer's rights), the endpoint's own `PERMISSIONS` clause was the only gate — open to everyone for a `PERMISSIONS FULL` endpoint. The `api::invoke()` function was affected the same way, resolving against the session's selected namespace/database (settable via the `surreal-ns` / `surreal-db` headers or `USE`). ### Impact What an attacker **can** do: - With valid credentials for any one namespace/database (a `VIEWER` is enough), invoke a custom API in another namespace/database by naming the victim scope in the URL. - Read data that endpoint returns — including from `PERMISSIONS NONE` tables, since the handler runs with permissions disabled — or trigger any writes and side effects it performs.

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.
04 / Limits
What this report cannot establish
- 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.
