EPSS Score99.8%

EPSS (Exploit Prediction Scoring System) estimates a 99.8% chance this CVE is exploited in the wild within the next 30 days — higher than 100% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

NETGEAR confirmed multiple routers allow unauthenticated web pages to pass form input directly to the command-line interface, permitting remote code execution.
