HighCVSS 8.6 · v3.1KEVWeaponized No fix recorded

Noroxi assessment

Priority: This week (action score 64/100)

  • CISA has confirmed exploitation in the wild (Jun 3, 2025). Remediation deadline for US federal agencies: Jun 24, 2025.
  • Probability of exploitation in the next 30 days: 0.78% (FIRST EPSS); higher than 56.5% of all records.
  • Someone with local access to the system 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.
  • According to the record, no fixed version is available yet.

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.
