Local security-feature bypass
Published May 12, 2026 · Updated May 12, 2026
Improper access control in Microsoft Windows Filtering Platform allows local users to bypass a security feature on affected Windows builds. Microsoft has not disclosed the WFP operation, object, or access-control check that incorrectly accepts attacker-controlled input. Low-privilege local access is required; the reported result is limited to confidentiality and integrity effects, with no service interruption.
