GHSA-3f95-w5h5-fq86 is a security vulnerability in mergify. O3 Security confirms whether GHSA-3f95-w5h5-fq86 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Prototype Pollution in mergify
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
mergifynpmDescription
All versions of mergify are vulnerable to Prototype Pollution. The mergify() function allows attackers to modify the prototype of Object causing the addition or modification of an existing property that will exist on all objects.
Recommendation
No fix is currently available. Consider using an alternative module as the package is deprecated.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mergify. 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 mergify has shipped for GHSA-3f95-w5h5-fq86 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-3f95-w5h5-fq86 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-3f95-w5h5-fq86. 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-3f95-w5h5-fq86 in your dependencies?
O3 detects GHSA-3f95-w5h5-fq86 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
