Some Drupal code (core, contrib, and custom) may be performing file operations on insufficiently validated user input, thereby being exposed to this vulnerability. This vulnerability is mitigated by the fact that such code paths typically require access to an administrative permission or an atypical configuration.","published":"2019-01-22T15:29:01.000Z","lastModified":"2026-06-17T02:39:02.000Z","status":"Modified","sourceIdentifier":"mlhess@drupal.org","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-20"],"affected":["drupal/drupal","debian/debian linux"],"epss":{"score":0.35577,"percentile":0.98445,"date":"2026-10-26","history":[{"date":"2026-09-21","score":0.27372,"percentile":0.98022},{"date":"2026-09-22","score":0.33228,"percentile":0.98294},{"date":"2026-09-25","score":0.35577,"percentile":0.98403}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 35.6%, higher than 98% of all known CVEs.
