Aug 2026: Microsoft PowerShell Remote Code Execution Vulnerability
CVE-2026-70337 Published on August 11, 2026
Microsoft PowerShell Remote Code Execution Vulnerability
Relative path traversal in Microsoft PowerShell Core 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.
