{"id":"GHSA-3gx6-h57h-rm27","aliases":["CVE-2019-6340","DRUPAL-CORE-2019-003"],"title":"Drupal Core Remote Code Execution Vulnerability","description":"Some field types do not properly sanitize data from non-form sources in Drupal 8.5.x before 8.5.11 and Drupal 8.6.x before 8.6.10. 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in use.)","severity":"high","score":8.1,"published":"2022-05-13T01:22:41.000Z","modified":"2025-12-10T23:41:09.322Z","withdrawn":false,"knownExploited":true,"affected":[{"ecosystem":"Packagist","name":"drupal/core","ranges":[{"events":[{"introduced":"8.6.0"},{"fixed":"8.6.10"}],"type":"ECOSYSTEM"}],"versions":["8.6.0","8.6.1","8.6.2","8.6.3","8.6.4","8.6.5","8.6.6","8.6.7","8.6.8","8.6.9"],"fixed":["8.6.10"]},{"ecosystem":"Packagist","name":"drupal/core","ranges":[{"events":[{"introduced":"7.0.0"},{"fixed":"7.62.0"}],"type":"ECOSYSTEM"}],"versions":[],"fixed":["7.62.0"]},{"ecosystem":"Packagist","name":"drupal/core","ranges":[{"events":[{"introduced":"8.0.0"},{"fixed":"8.5.11"}],"type":"ECOSYSTEM"}],"versions":["8.0.0","8.0.1","8.0.2","8.0.3","8.0.4","8.0.5","8.0.6","8.1.0","8.1.0-beta1","8.1.0-beta2","8.1.0-rc1","8.1.1","8.1.10","8.1.2","8.1.3","8.1.4","8.1.5","8.1.6","8.1.7","8.1.8","8.1.9","8.2.0","8.2.0-beta1","8.2.0-beta2","8.2.0-beta3","8.2.0-rc1","8.2.0-rc2","8.2.1","8.2.2","8.2.3","8.2.4","8.2.5","8.2.6","8.2.7","8.2.8","8.3.0","8.3.0-alpha1","8.3.0-beta1","8.3.0-rc1","8.3.0-rc2","8.3.1","8.3.2","8.3.3","8.3.4","8.3.5","8.3.6","8.3.7","8.3.8","8.3.9","8.4.0","8.4.0-alpha1","8.4.0-beta1","8.4.0-rc1","8.4.0-rc2","8.4.1","8.4.2","8.4.3","8.4.4","8.4.5","8.4.6","8.4.7","8.4.8","8.5.0","8.5.0-alpha1","8.5.0-beta1","8.5.0-rc1","8.5.1","8.5.10","8.5.2","8.5.3","8.5.4","8.5.5","8.5.6","8.5.7","8.5.8","8.5.9"],"fixed":["8.5.11"]},{"ecosystem":"Packagist","name":"drupal/drupal","ranges":[{"events":[{"introduced":"7.0.0"},{"fixed":"7.62.0"}],"type":"ECOSYSTEM"}],"versions":[],"fixed":["7.62.0"]},{"ecosystem":"Packagist","name":"drupal/drupal","ranges":[{"events":[{"introduced":"8.0.0"},{"fixed":"8.5.11"}],"type":"ECOSYSTEM"}],"versions":["8.0.0","8.0.1","8.0.2","8.0.3","8.0.4","8.0.5","8.0.6","8.1.0","8.1.0-beta1","8.1.0-beta2","8.1.0-rc1","8.1.1","8.1.10","8.1.2","8.1.3","8.1.4","8.1.5","8.1.6","8.1.7","8.1.8","8.1.9","8.2.0","8.2.0-beta1","8.2.0-beta2","8.2.0-beta3","8.2.0-rc1","8.2.0-rc2","8.2.1","8.2.2","8.2.3","8.2.4","8.2.5","8.2.6","8.2.7","8.2.8","8.3.0","8.3.0-alpha1","8.3.0-beta1","8.3.0-rc1","8.3.0-rc2","8.3.1","8.3.2","8.3.3","8.3.4","8.3.5","8.3.6","8.3.7","8.3.8","8.3.9","8.4.0","8.4.0-alpha1","8.4.0-beta1","8.4.0-rc1","8.4.0-rc2","8.4.1","8.4.2","8.4.3","8.4.4","8.4.5","8.4.6","8.4.7","8.4.8","8.5.0","8.5.0-alpha1","8.5.0-beta1","8.5.0-rc1","8.5.1","8.5.10","8.5.2","8.5.3","8.5.4","8.5.5","8.5.6","8.5.7","8.5.8","8.5.9"],"fixed":["8.5.11"]},{"ecosystem":"Packagist","name":"drupal/drupal","ranges":[{"events":[{"introduced":"8.6.0"},{"fixed":"8.6.10"}],"type":"ECOSYSTEM"}],"versions":["8.6.0","8.6.1","8.6.2","8.6.3","8.6.4","8.6.5","8.6.6","8.6.7","8.6.8","8.6.9"],"fixed":["8.6.10"]}],"references":["https://nvd.nist.gov/vuln/detail/CVE-2019-6340","https://github.com/FriendsOfPHP/security-advisories/blob/master/drupal/core/CVE-2019-6340.yaml","https://github.com/FriendsOfPHP/security-advisories/blob/master/drupal/drupal/CVE-2019-6340.yaml","https://github.com/drupal/drupal","https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2019-6340","https://www.drupal.org/sa-core-2019-003","https://www.exploit-db.com/exploits/46452","https://www.exploit-db.com/exploits/46459","https://www.exploit-db.com/exploits/46510","https://www.synology.com/security/advisory/Synology_SA_19_09"],"sources":[{"name":"OSV","id":"GHSA-3gx6-h57h-rm27","modified":"2025-12-10T23:41:09.322988Z","url":"https://osv.dev/vulnerability/GHSA-3gx6-h57h-rm27"}],"assessments":[{"source":"OSV","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:H","score":8.1}]}
