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.","published":"2024-12-09T23:26:30.780Z","modified":"2026-07-15T01:49:18.885728509Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00956,"percentile":0.58103,"asOf":"2026-08-08"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"drupal/core","fixedVersion":"10.2.11"},{"ecosystem":"Packagist","name":"drupal/core","fixedVersion":"10.3.9"},{"ecosystem":"Packagist","name":"drupal/core","fixedVersion":"7.102"},{"ecosystem":"Packagist","name":"drupal/core-recommended","fixedVersion":"10.2.11"},{"ecosystem":"Packagist","name":"drupal/core-recommended","fixedVersion":"10.3.9"},{"ecosystem":"Packagist","name":"drupal/core-recommended","fixedVersion":"7.102"},{"ecosystem":"Packagist","name":"drupal/drupal","fixedVersion":"10.2.11"},{"ecosystem":"Packagist","name":"drupal/drupal","fixedVersion":"10.3.9"},{"ecosystem":"Packagist","name":"drupal/drupal","fixedVersion":"7.102"}],"fix":null,"references":[{"type":"WEB","url":"https://git.drupalcode.org/project/drupal"},{"type":"WEB","url":"https://www.drupal.org/project/drupal/"},{"type":"WEB","url":"https://www.drupal.org/sa-core-2024-008"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/55xxx/CVE-2024-55638.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-55638"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:18.885728509Z"}}
