Noroxi assessment

Priority: This week (action score 66/100)

  • CISA has confirmed exploitation in the wild (Mar 13, 2026). Remediation deadline for US federal agencies: Mar 27, 2026.
  • Probability of exploitation in the next 30 days: 2.3% (FIRST EPSS); higher than 83.5% 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) 146.0.3856.62.

Don’t wait for the next maintenance window. Upgrade to Microsoft Edge (Chromium-based) 146.0.3856.62 or later.
