Overview

AI description

Automated description summarized from trusted sources.

CVE-2026-32202 is a protection mechanism failure vulnerability found in Windows Shell that allows an unauthorized attacker to perform spoofing over a network. This flaw enables attackers to bypass security controls designed to prevent spoofing attacks, potentially leading to information disclosure through deception of users or security controls. The vulnerability can be exploited by enticing a user to interact with malicious content over a network connection, often involving specially crafted Windows shortcut (LNK) files that leverage Universal Naming Convention (UNC) paths. This can lead to authentication coercion and credential theft, as the system may automatically authenticate to an attacker's server without direct user interaction. This vulnerability has been linked to an incomplete patch for a previous Windows Shell security bypass (CVE-2026-21510).
