An authenticated administrator can inject malicious Smarty expressions into email templates via the messages configuration interface, and when the template is previewed or rendered, functions such as system(), exec(), file_put_contents(), and file_get_contents() can be executed with the privileges of the web process. This allows arbitrary OS command execution, file read/write operations, and RCE on the underlying server.","published":"2026-10-12T15:17:06.000Z","lastModified":"2026-10-15T17:17:11.000Z","status":"Deferred","sourceIdentifier":"cret@cert.org","cvss":{"version":"3.1","score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"},"cwe":["CWE-1336"],"affected":[],"epss":{"score":0.00517,"percentile":0.43712,"date":"2026-10-26","history":[{"date":"2026-10-13","score":0.00401,"percentile":0.32483}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.52%).
