GHSA-f37v-82c4-4x64 is a low-severity (CVSS 2.8) NULL Pointer Dereference vulnerability in electron. O3 Security confirms whether GHSA-f37v-82c4-4x64 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Electron: Crash in clipboard.readImage() on malformed clipboard image data
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.
electronnpmDescription
Impact
Apps that call clipboard.readImage() may be vulnerable to a denial of service. If the system clipboard contains image data that fails to decode, the resulting null bitmap is passed unchecked to image construction, triggering a controlled abort and crashing the process.
Apps are only affected if they call clipboard.readImage(). Apps that do not read images from the clipboard are not affected. This issue does not allow memory corruption or code execution.
Workarounds
Validate that the clipboard contains image data via clipboard.availableFormats() before calling clipboard.readImage(). Note this only narrows the window — upgrading to a fixed version is recommended.
Fixed Versions
42.0.0-alpha.541.1.040.8.539.8.5

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 39.8.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f37v-82c4-4x64 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-f37v-82c4-4x64 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-f37v-82c4-4x64. 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-f37v-82c4-4x64 in your dependencies?
O3 detects GHSA-f37v-82c4-4x64 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
