Improper Privilege Management

Are you affected? Scan for Free

TL;DR

A <webview> tag can enable Node.js integration inside its Web Workers even when the embedding app disabled Node.js integration for that guest. Guest content loaded in the <webview> gains more privilege than the embedder configured, exposing Node.js APIs to workers spawned from untrusted content. This affects apps that enable the <webview> tag with an unsandboxed embedder. The fix propagates the embedder's Node.js integration restriction to Web Workers spawned inside the guest.

How do I fix this?

Upgrade the electron library to the patch version.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range and you enable the <webview> tag with an unsandboxed embedder.
