HighCVSS 8.8 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 38/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 8.6% (FIRST EPSS); higher than 95.2% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Microsoft Edge (Chromium-based) 140.0.3485.94.

Low priority for now. Upgrade to Microsoft Edge (Chromium-based) 140.0.3485.94 or later.
