WordPress MetForm plugin <= 3.8.3 - Broken Access Control vulnerability

Noroxi assessment

Priority: Monitor (action score 35/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.43% (FIRST EPSS).
  • 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.
  • Fixed version: Roxnor Metform 3.8.4.
  • Severity is disputed: the assigning authority (CNA) scores it 4.3, NVD 8.8.

Low priority for now. Upgrade to Roxnor Metform 3.8.4 or later.
