GHSA-m3c3-78fh-w3w7
GHSA-m3c3-78fh-w3w7 is a CWE-863 vulnerability. O3 Security confirms whether GHSA-m3c3-78fh-w3w7 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
SurrealDB before 2.3.6 deny-net Bypass via DNS Resolution
Description
SurrealDB before 2.2.6, 2.3.6, and 2.1.8 (and 3.0.0-alpha.7 and earlier) fails to validate DNS-resolved hostnames against --deny-net network access restrictions in its http::* functions. An authenticated user can invoke http::<fn>(<url>) with a hostname that resolves to a denied IP address, causing the server to issue the request anyway and return the response. This bypasses network access controls, allowing access to restricted internal endpoints and potentially retrieving or altering sensitive information and credentials, depending on the deployment.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for GHSA-m3c3-78fh-w3w7 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 pinpoints whether GHSA-m3c3-78fh-w3w7 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-m3c3-78fh-w3w7. 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-m3c3-78fh-w3w7 in your dependencies?
O3 detects GHSA-m3c3-78fh-w3w7 across dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
