CVE-2024-55638 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Deserialization of Untrusted Data vulnerability in Drupal Core allows Object Injection.This issue affects Drupal Core: from 7.0 before 7.102, from 8.0.0 before 10.2.11, from 10.3.0 before 10.3.9. Drupal core contains a chain of methods that is exploitable when an insecure deserialization vulnerability exists on the site. This so-called gadget chain presents no direct threat but is a vector that can be used to achieve remote code execution if the application deserializes untrusted data due to another vulnerability.. EPSS estimates a 0.96% chance of exploitation in the next 30 days.
