Improper Link Resolution in WatchDog Anti-Virus on Windows

CVE-2026-92253

What is CVE-2026-92253?

A vulnerability exists in the quarantine restoration process of WatchDog Anti-Virus 1.8.640 on Windows, where improper link resolution before file access could allow local, low-privileged attackers to manipulate filesystem behavior. By creating a directory junction at the original file path and convincing an administrator to restore a quarantined file, attackers could potentially redirect the file to an arbitrary filesystem location. This exploitation could result in the modification of protected files or even unauthorized execution of SYSTEM-level code through techniques such as DLL hijacking.
