How severe is GHSA-qqvq-6xgj-jw8g?

GHSA-qqvq-6xgj-jw8g has a CVSS score of 8.8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-qqvq-6xgj-jw8g?

GHSA-qqvq-6xgj-jw8g affects the following packages: electron (npm), electron (npm), electron (npm), electron (npm), electron (npm). Ecosystems affected: npm.

How do I fix GHSA-qqvq-6xgj-jw8g?

Update electron to 22.3.25 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qqvq-6xgj-jw8g is resolved across your whole dependency graph.

How do I detect GHSA-qqvq-6xgj-jw8g 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-qqvq-6xgj-jw8g if there is no patch (or I can't update yet)?

Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.

Is GHSA-qqvq-6xgj-jw8g actively exploited in the wild?

Yes. There are 9 known exploit references for GHSA-qqvq-6xgj-jw8g, including 8 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-qqvq-6xgj-jw8g?

GHSA-qqvq-6xgj-jw8g has an EPSS (Exploit Prediction Scoring System) score of 49.0%, placing it in the 99th 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 warrants monitoring and prompt remediation.

Is GHSA-qqvq-6xgj-jw8g in the CISA Known Exploited Vulnerabilities catalog?

Yes. GHSA-qqvq-6xgj-jw8g (Google Chromium libvpx Heap Buffer Overflow Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2023-10-02. CISA required all US federal civilian agencies to remediate this vulnerability by 2023-10-23. The required action was: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is GHSA-qqvq-6xgj-jw8g?

GHSA-qqvq-6xgj-jw8g is classified as Out-of-bounds Write (CWE-787). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-qqvq-6xgj-jw8g published, and has it been updated?

GHSA-qqvq-6xgj-jw8g was published on September 28, 2023 and was last updated on September 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
