A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.

Details
A <webview> could enable Node.js integration in its Web Workers even when its embedder had Node.js integration disabled, giving guest content more privilege than the embedder allowed.
Apps are only affected if they enable the <webview> tag and the embedder is unsandboxed. Apps that do not use <webview>, or that keep the embedder sandboxed, are not affected.
Remove nodeIntegrationInWorker from the guest preferences in a will-attach-webview handler, or do not enable the <webview> tag when loading untrusted content.

Refreshed 11/14/2026, via FIRST.org's EPSS model, not CVSS, this measures likelihood of exploitation, not how severe it would be.
