HighCVSS 7.8 · v3.0—Proof of concept No fix recorded

Noroxi assessment

Priority: Plan (action score 46/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 49.8% (FIRST EPSS); higher than 98.9% 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.

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