Windows Filtering Platform (WFP) Security Feature Bypass Vulnerability

Published May 12, 2026 · Updated May 12, 2026

Summary

Impact: Security Feature Bypass. Microsoft rating: Important. Not known to be exploited — Exploitation Unlikely. Customer action: Required.

Details

What kind of security feature could be bypassed by successfully exploiting this vulnerability?
Successfully exploiting this vulnerability could allow an attacker to bypass network security protections that rely on Fully Qualified Domain Name (FQDN)‑based rules, such as policies that block or allow network connections based on domain names. This could reduce the effectiveness of security features that depend on those domain‑based network controls.

According to the CVSS metrics, successful exploitation of this vulnerability could lead to some loss of confidentiality (C:L), and integrity (I:L) but lead to no loss of availability (A:N). What is the impact of this vulnerability?
Successful exploitation allows limited tampering with security configuration (low integrity impact) but does not expose sensitive data or disrupt system availability. In short, the vulnerability weakens specific security enforcement controls without causing data disclosure or service outages.
