Sep 2026: Windows URL Moniker Security Feature Bypass Vulnerability
CVE-2026-73019 Published on September 8, 2026
Windows URL Moniker Security Feature Bypass Vulnerability
Improper resolution of path equivalence in Windows URL Moniker allows an unauthorized attacker to bypass a security feature over a network.
Weakness Type
Improper Resolution of Path Equivalence
The system or application is vulnerable to file system contents disclosure through path equivalence. Path equivalence involves the use of special characters in file and directory names. The associated manipulations are intended to generate multiple names for the same object. Path equivalence is usually employed in order to circumvent access controls expressed using an incomplete set of file name or file path representations. This is different from path traversal, wherein the manipulations are performed to generate a name for a different object.
