Noroxi assessment

Priority: Monitor (action score 30/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.78% (FIRST EPSS); higher than 56.2% 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. Special conditions such as timing or configuration are required.
  • Fixed version: Microsoft Edge (Chromium-based) 126.0.2592.113.

Low priority for now. Upgrade to Microsoft Edge (Chromium-based) 126.0.2592.113 or later.
