CVE-2025-59214 is a Windows File Explorer spoofing and sensitive-information-disclosure vulnerability affecting shortcut-file processing. It was reported as a further bypass of prior fixes for CVE-2025-24054 and CVE-2025-50154. File Explorer inconsistently validates shortcut values: icon-path handling receives the intended security check, while a shortcut target containing a UNC path can take a separate existence-check path. That alternate path can initiate NTLM authentication to an attacker-controlled network service and disclose NTLMv2-SSP authentication material without user interaction.

A zero-click bypass of prior Windows NTLM credential-leak mitigations. A crafted LNK file with a UNC target can automatically trigger NTLM authentication and disclose NTLMv2-SSP hashes, enabling offline cracking or NTLM relay attacks that may lead to unauthorized access, lateral movement, privilege escalation, or RCE.
Windows File Explorer spoofing issue referenced in the context of preventing NTLM credential leakage / sensitive information leakage over the network.
A Windows File Explorer issue (described as a spoofing issue) that can be leveraged to leak sensitive information (NTLM credentials/hashes) over the network, apparently via preview-related behavior and external path references.
