How severe is GHSA-3qxv-5xgr-q7w9?

GHSA-3qxv-5xgr-q7w9 has a CVSS score of 3.9/10, rated LOW. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-3qxv-5xgr-q7w9?

GHSA-3qxv-5xgr-q7w9 affects the following packages: electron (npm), electron (npm), electron (npm), electron (npm). Ecosystems affected: npm.

How do I fix GHSA-3qxv-5xgr-q7w9?

Update electron to 42.11.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3qxv-5xgr-q7w9 is resolved across your whole dependency graph.

How do I detect GHSA-3qxv-5xgr-q7w9 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for electron, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-3qxv-5xgr-q7w9 if there is no patch (or I can't update yet)?

Stop feeding it untrusted input: reject or quarantine files and payloads from unverified sources until you can upgrade, restrict accepted formats to the ones you actually need, and run the parsing or decoding step in a least-privileged sandbox or short-lived worker so a crash or corrupted read cannot reach the rest of the process.

Is GHSA-3qxv-5xgr-q7w9 actively exploited in the wild?

No public exploit code has been indexed for GHSA-3qxv-5xgr-q7w9 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-3qxv-5xgr-q7w9?

GHSA-3qxv-5xgr-q7w9 has an EPSS (Exploit Prediction Scoring System) score of 0.1%, placing it in the 3th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-3qxv-5xgr-q7w9?

GHSA-3qxv-5xgr-q7w9 is classified as Out-of-bounds Read (CWE-125). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-3qxv-5xgr-q7w9 published, and has it been updated?

GHSA-3qxv-5xgr-q7w9 was published on October 22, 2026 and was last updated on October 22, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

Frame data received from the GPU process for webContents.beginFrameSubscription was not fully validated by the main process. A compromised GPU process could cause the main process to read out-of-bounds memory while producing the captured frame images, disclosing memory or crashing the app.

Apps are only affected if they use webContents.beginFrameSubscription and an attacker has separately gained code execution in the GPU process. Apps that do not subscribe to captured frames are not affected.

Workarounds

There are no app side workarounds, you must update to a patched version of Electron.

Fixed Versions

45.0.0-alpha.9
44.4.3
