MediumCVSS 5.4 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • 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: 0.18% (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: Facebook WhatsApp Business for iOS 2.25.23.82; Facebook WhatsApp Desktop for Mac 2.25.23.83; Facebook WhatsApp for iOS 2.25.23.73.

Low priority for now. Upgrade to Facebook WhatsApp Business for iOS 2.25.23.82; Facebook WhatsApp Desktop for Mac 2.25.23.83; Facebook WhatsApp for iOS 2.25.23.73 or later.
