EPSS Score100.0%

EPSS (Exploit Prediction Scoring System) estimates a 100.0% 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.

Drupal Core contains a remote code execution vulnerability that could allow an attacker to exploit multiple attack vectors on a Drupal site, resulting in complete site compromise.
