Noroxi assessment

Priority: This week (action score 71/100)

  • CISA has confirmed exploitation in the wild (Feb 3, 2026). Remediation deadline for US federal agencies: Feb 24, 2026.
  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 36.1% (FIRST EPSS); higher than 98.4% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Feb 3, 2026. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Feb 24, 2026.
