GHSA-qfcv-5whw-7pcw is a critical-severity (CVSS 9.6) Information Exposure vulnerability in aegir. O3 Security confirms whether GHSA-qfcv-5whw-7pcw is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Exposure of Sensitive Information to an Unauthorized Actor in AEgir
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
aegirnpmDescription
Impact
aegir publish and aegir build may leak secrets from environmental variables in the browser bundle published to npm.
Patches
The code has been patched, users should upgrade to >= 21.10.1
Workarounds
Run printenv to check your environment variables and revoke any secrets.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for aegir. 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.
Fix
Update aegir to 21.10.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qfcv-5whw-7pcw 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 pinpoints whether GHSA-qfcv-5whw-7pcw 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-qfcv-5whw-7pcw. 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-qfcv-5whw-7pcw in your dependencies?
O3 detects GHSA-qfcv-5whw-7pcw across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
