GHSA-22cc-w7xm-rfhx
GHSA-22cc-w7xm-rfhx is a CWE-863 vulnerability in mezzanine. O3 Security confirms whether GHSA-22cc-w7xm-rfhx is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mezzanine. 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 mezzanine has shipped for GHSA-22cc-w7xm-rfhx 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-22cc-w7xm-rfhx 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-22cc-w7xm-rfhx. 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-22cc-w7xm-rfhx in your dependencies?
O3 detects GHSA-22cc-w7xm-rfhx across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
