CVE-2026-83651: Windows GDI Information Disclosure Vulnerability

HighCVSS 7.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 1% (FIRST EPSS); higher than 64.5% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Microsoft Office 365 for Mac 16.114.26101123; Microsoft Office for Android 16.0.20430.20000; Microsoft Office LTSC for Mac 2021 16.114.26101123.

Low priority for now. Upgrade to Microsoft Office 365 for Mac 16.114.26101123; Microsoft Office for Android 16.0.20430.20000; Microsoft Office LTSC for Mac 2021 16.114.26101123 or later.
