GHSA-f9mq-jph6-9mhm
MEDIUMGHSA-f9mq-jph6-9mhm is a medium-severity (CVSS 6.8) CWE-552 vulnerability in electron. O3 Security confirms whether GHSA-f9mq-jph6-9mhm is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Arbitrary file read via window-open IPC in Electron
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.
electronnpmDescription
Impact
The vulnerability allows arbitrary local file read by defining unsafe window options on a child window opened via window.open.
Workarounds
Ensure you are calling event.preventDefault() on all new-window events where the url or options is not something you expect.
Fixed Versions
9.0.0-beta.218.2.47.2.4

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for electron. 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 electron to 7.2.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f9mq-jph6-9mhm 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-f9mq-jph6-9mhm 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-f9mq-jph6-9mhm. 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-f9mq-jph6-9mhm in your dependencies?
O3 detects GHSA-f9mq-jph6-9mhm across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
