Senserva AI Opinion for CVE-2018-7600
Drupalgeddon2 needs little introduction: unauthenticated remote code execution against Drupal Core with a 100 percent EPSS score, confirmed ransomware use, and complete site compromise as the documented outcome. Mass exploitation began within two weeks of the patch and never fully stopped, sweeping up forgotten microsites and campaign pages that outlived their owners. Critical Severity at CVSS 9.8.
