MediumCVSS 6.2 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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: 0.12% (FIRST EPSS).
  • Someone with local access to the system 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 Edge (Chromium-based) 151.0.4129.59.

Low priority for now. Upgrade to Microsoft Edge (Chromium-based) 151.0.4129.59 or later.
