CVE-2026-92253 is a medium-severity vulnerability rated 5.2/10 on the CVSS scale. Improper link resolution before file access in the quarantine restoration process of WatchDog Anti-Virus 1.8.640 on Windows allows local, low-privileged attackers to cause a quarantined file to be written to an arbitrary filesystem location by creating a directory junction at the original file path and persuading an administrator to restore the file. This may enable modification of protected files or SYSTEM-level code execution through DLL hijacking.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
