Noroxi assessment

Priority: Plan (action score 47/100)

  • CISA has confirmed exploitation in the wild (Oct 30, 2026). Remediation deadline for US federal agencies: Nov 13, 2026.
  • Probability of exploitation in the next 30 days: 0.82% (FIRST EPSS); higher than 57.7% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.
