CVE-2026-57988 Published on July 3, 2026
Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability
Relative path traversal in Microsoft Edge (Chromium-based) allows an unauthorized attacker to execute code over a network.
Weakness Type
Relative Path Traversal
The software uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. This allows attackers to traverse the file system to access files or directories that are outside of the restricted directory.
