Threat actor UNC6485 exploited this flaw as early as August 24, 2025, bypassing authentication and chaining it with anti-virus feature abuse for code execution. The vulnerability affected Triofox version 16.4.10317.56372 and was patched in version 16.7.10368.56560. Attackers created admin accounts, deployed remote access tools, conducted reconnaissance, and attempted privilege escalation.
