What is CVE-2025-47181?

  • It is a critical security vulnerability found in Microsoft Edge, related to improper link resolution before file access, known as a "link following" exploit.
  • Exploitation of this flaw could allow an attacker with authorized access to elevate their privileges on the system by abusing how symbolic links or shortcuts are resolved.
