CVE-2026-62801 — Windows PowerShell Security Feature Bypass

Wed, 09 Sep 2026 00:00:00 +0000

Summary

A path traversal vulnerability in Windows PowerShell allows an unauthenticated attacker to bypass path validation safeguards over a network. Successful exploitation circumvents the security checks that restrict which files may be modified and that require user approval for sensitive locations, allowing changes to protected files without the user’s knowledge or consent.

The attack requires user interaction but no authentication. The impact is limited to integrity — an attacker can modify protected files but cannot read arbitrary files or cause denial of service through this vulnerability alone.
