CVE-2026-92253: Arbitrary File Write via Directory Junction in WatchDog Anti-Virus Quarantine Restoration

MediumCVSS 5.2 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 20/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No special conditions are required; it is repeatable.
  • Fixed version: WatchDog Anti-Virus 1.8.804.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to WatchDog Anti-Virus 1.8.804 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
