electron is vulnerable to Use After Free
88
High Risk
This Affects:
electronTL;DR
electron's embedded Chromium DOM can free element attribute storage while batch attribute updates still reference it. Crafted HTML that manipulates element attributes during batch notifications can trigger the use-after-free. Pre-fix versions risk sandboxed arbitrary code execution. The backport uses index-based cloning, stronger attribute batch checks, forbidden event dispatch scopes, and safer slider element construction.

You are affected if you are using a version that falls within the vulnerable range.
Background info
electron is vulnerable to Use After Free in versions 40.0.0 - 40.10.2 and 41.0.0 - 41.7.1.
