Where this sits among everything scored
Real-World Exposure
surrealdbReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
The query executor would panic when executing a query containing a call to a built-in SurrealDB function that did not exist. This could occur accidentally in situations where the version of the SurrealDB client was newer than the SurrealDB server or when a pre-parsed query was provided to the server via a newer version of the SurrealDB SDK.
Impact
A client that is authorized to run queries in a SurrealDB server is able to craft and execute a pre-parsed query invoking a nonexistent built-in function, which will cause a panic. This will crash the server, leading to denial of service.
Patches
- Version 1.2.0 and later are not affected by this issue.
Workarounds
Concerned users unable to update may want to limit the ability of untrusted users to run arbitrary SurrealQL queries in the affected versions of SurrealDB. To limit the impact of the denial of service, SurrealDB administrators may also want to ensure that the SurrealDB process is running so that it can be automatically re-started after a crash.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for surrealdb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update surrealdb to 1.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6wr5-jmpr-mjcx is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
