SurrealDB: USE NS/DB implicit creation bypasses DEFINE authorization
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.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
6.5 medium
GitHub source severity; exploitability and local consequence require separate evidence.

source listed< 3.1.0
An anonymous caller could create new namespaces and databases on a running SurrealDB instance without holding `DEFINE NAMESPACE` or `DEFINE DATABASE` permission. `USE NS ` and `USE DB ` automatically create the target when it does not exist. The three places `USE` is handled — the RPC `use` method, `Datastore::process_use`, and the SurrealQL executor — did not check whether the caller was allowed to create the resource. Under default capabilities any session reached this path, including an unauthenticated guest. ### Impact What an attacker **can** do: - Create new namespaces and databases without `DEFINE NAMESPACE` / `DEFINE DATABASE` permission. An unauthenticated guest is enough under default capabilities. - Recreate a parent namespace that an operator deliberately dropped, using a stale namespace-Editor token, by running `USE NS DB anything`. - Exhaust catalog storage by repeatedly creating new resources. What it **can't** do: - Read or modify data inside any pre-existing namespace or database. - Escalate to root or namespace-owner privileges on existing resources. - Affect deployments running with `auth_enabled=false`. ### Patches All three `USE` e
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.
