Application crash via oversized command-line input
Published Jan 30, 2026 · Updated Jan 30, 2026
Denial of service in WinFrigate Frigate 2.02 allows local users to crash the application through oversized command-line input. The command-line field accepts an 8,000-character repeated payload without enforcing an effective input limit, and processing it terminates Frigate. Exploitation requires local access and active interaction with the graphical interface; the documented consequence is an application crash.
