EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-6r8p-hpg7-825g plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,166 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
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
In some specific instances, the SurrealQL parser will attempt to recursively parse nested statements or idioms (i.e. nested IF and RELATE statements, nested basic idioms and nested access to attributes) without checking if the depth limit established by default or in the SURREAL_MAX_COMPUTATION_DEPTH environment variable is exceeded. This can lead to the stack overflowing when the nesting surpasses certain levels of depth.
Impact
An attacker that is authorized to run queries on a SurrealDB server may be able to run a query using the affected statements and idioms with very deep nesting in order to crash the server, leading to denial of service.
Patches
- Version 1.1.0 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.

Detection & mitigation playbook
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 1.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6r8p-hpg7-825g is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-6r8p-hpg7-825g can be triaged on real exposure rather than presence alone.
Tailored to GHSA-6r8p-hpg7-825g. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-6r8p-hpg7-825g in your dependencies?
O3 Security finds GHSA-6r8p-hpg7-825g across crates.io dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
