Noroxi assessment

Priority: Monitor (action score 35/100)

  • Probability of exploitation in the next 30 days: 0.37% (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: MultiVendorX WC Marketplace 4.1.4.

Low priority for now. Upgrade to MultiVendorX WC Marketplace 4.1.4 or later.
