Which packages are affected by GHSA-x562-297c-g43g?

GHSA-x562-297c-g43g affects the following packages: electron (npm), electron (npm), electron (npm), electron (npm). Ecosystems affected: npm.

How do I fix GHSA-x562-297c-g43g?

Update electron to 45.0.0-alpha.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-x562-297c-g43g is resolved across your whole dependency graph.

How do I detect GHSA-x562-297c-g43g 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-x562-297c-g43g if there is no patch (or I can't update yet)?

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.

Is GHSA-x562-297c-g43g actively exploited in the wild?

No public exploit code has been indexed for GHSA-x562-297c-g43g 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-x562-297c-g43g?

GHSA-x562-297c-g43g has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 10th 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-x562-297c-g43g?

GHSA-x562-297c-g43g is classified as CWE-346 (CWE-346). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-x562-297c-g43g published, and has it been updated?

GHSA-x562-297c-g43g 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

For pointerLock permission requests made from some cross-origin iframes, session.setPermissionRequestHandler() was given the top-level frame's requestingUrl and isMainFrame instead of the requesting frame's. Apps that grant pointer lock based on the requesting origin could grant it to embedded content under the top-level page's identity.

Apps are only affected if they embed untrusted content in iframes and decide pointerLock requests by origin in setPermissionRequestHandler. Apps that do not embed untrusted content, or that deny pointerLock for it, are not affected.

Workarounds

Deny the pointerLock permission for web contents that embed untrusted frames.
