Microsoft Edge - Chromium-based Browser

Microsoft CVSS 8.8 Updated May 29, 2026

Executive Risk Summary

"A remote code execution vulnerability exists in Microsoft Edge (Chromium-based) that allows an attacker to execute arbitrary code on the target system. This vulnerability can be exploited by an unauthenticated attacker, potentially leading to a complete system compromise."

Anticipated Attack Path

  1. 1. Initial Exploitation: Attacker sends a malicious payload to the victim's Microsoft Edge browser
  2. 2. Privilege Escalation: Attacker gains elevated privileges on the system
  3. 3. Lateral Movement: Attacker moves laterally within the network, exploiting other vulnerable systems

Am I Vulnerable?

  • Verify Microsoft Edge version and ensure it is up-to-date
  • Monitor system logs for suspicious activity
  • Implement a web application firewall (WAF) to detect and prevent exploitation attempts
