lnk vulnerability

About this tag
The lnk vulnerability tag covers a critical Windows shortcut file flaw, tracked as CVE-2025-9491 and ZDI-CAN-25373, that allows attackers to hide malicious commands in .lnk files by padding them with whitespace or non-printing characters. This UI misrepresentation bug lets crafted shortcuts display a benign Target field while executing hidden code, and it has been actively exploited by nation-state espionage groups and cybercriminals. Discussions include the lack of an official patch, the vulnerability's use in targeted campaigns, and Microsoft's classification of it as a UI flaw rather than a critical security issue. The tag also touches on related Windows security topics such as zero-day exploits and shortcut abuse.
