Noroxi assessment

Priority: This week (action score 66/100)

  • CISA has confirmed exploitation in the wild (Sep 4, 2026). Remediation deadline for US federal agencies: Sep 18, 2026.
  • Probability of exploitation in the next 30 days: 1.8% (FIRST EPSS); higher than 78.8% 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) 152.0.4191.62.
  • Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Upgrade to Microsoft Edge (Chromium-based) 152.0.4191.62 or later.

Vulnrichment: CISA's decision-tree inputs.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Sep 4, 2026. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Sep 18, 2026.
