In the generated form.lib.php file, upload file types are checked against a hard-coded list of dangerous extensions. This list does not include all variations of PHP files, which may lead to execution of the contained PHP code if the attacker can guess the uploaded filename. The form by default appends a short random string to the end of the filename.","published":"2018-07-13T20:29:02.000Z","lastModified":"2026-06-17T00:56:10.000Z","status":"Modified","sourceIdentifier":"cret@cert.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-434"],"affected":["jqueryform/php formmail generator"],"epss":{"score":0.03332,"percentile":0.88561,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (3.33%).
