35th percentile — higher than 35% of all known CVEs

A Use-After-Free vulnerability in Microsoft Edge (Chromium-based) allows an unauthorized attacker to execute code over a network. The issue stems from improper memory management when processing specially crafted network requests.

An attacker can remotely execute arbitrary code in the browser context, potentially leading to system compromise, data theft, or malware installation.

Immediately update Microsoft Edge to the latest version available from the official repository. Implement policies to block unknown or suspicious scripts and restrict access to unauthorized websites.
