This can lead to arbitrary PHP code execution in some cases. A site is only affected by this if one of the following conditions is met: The site has the Drupal 8 core RESTful Web Services (rest) module enabled and allows PATCH or POST requests, or the site has another web services module enabled, like JSON:API in Drupal 8, or Services or RESTful Web Services in Drupal 7. (Note: The Drupal 7 Services module itself does not require an update at this time, but you should apply other contributed updates associated with this advisory if Services is in use.)","published":"2019-02-21T21:29:00.343Z","modified":"2026-07-08T20:57:44.285496Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.92017,"percentile":0.99812,"asOf":"2026-08-22"},"cisaKev":{"dateAdded":"2022-03-25","dueDate":"2022-04-15","knownRansomwareCampaignUse":false},"exploitsKnown":24,"affectedPackages":[{"ecosystem":"Packagist","name":"drupal/core","fixedVersion":"8.6.10"},{"ecosystem":"Packagist","name":"drupal/core","fixedVersion":"7.62.0"},{"ecosystem":"Packagist","name":"drupal/core","fixedVersion":"8.5.11"},{"ecosystem":"Packagist","name":"drupal/drupal","fixedVersion":"7.62.0"},{"ecosystem":"Packagist","name":"drupal/drupal","fixedVersion":"8.5.11"},{"ecosystem":"Packagist","name":"drupal/drupal","fixedVersion":"8.6.10"}],"fix":null,"references":[{"type":"WEB","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2019-6340"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/107106"},{"type":"ADVISORY","url":"https://www.drupal.org/sa-core-2019-003"},{"type":"ADVISORY","url":"https://www.synology.com/security/advisory/Synology_SA_19_09"},{"type":"FIX","url":"https://www.exploit-db.com/exploits/46452/"},{"type":"EVIDENCE","url":"https://www.exploit-db.com/exploits/46459/"},{"type":"EVIDENCE","url":"https://www.exploit-db.com/exploits/46510/"}],"provenance":{"sources":["OSV.dev","CISA KEV","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T20:57:44.285496Z"}}
