CVE-2026-113765: Windows File Server Resource Management Service Elevation of Privilege Vulnerability

HighCVSS 7.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.38% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Windows Server 2016 10.0.14393.9688; Windows Server 2016 (Server Core installation) 10.0.14393.9688; Windows Server 2019 10.0.17763.9487.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Windows Server 2016 10.0.14393.9688; Windows Server 2016 (Server Core installation) 10.0.14393.9688; Windows Server 2019 10.0.17763.9487 or later.
