CVE-2026-77897 Published on September 8, 2026
Microsoft Power Automate Desktop Elevation of Privilege Vulnerability
Relative path traversal in Power Automate allows an authorized attacker to elevate privileges locally.
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.
