NOTE: the Supplier's position is that plugins intentionally can contain arbitrary PHP code, and can only be installed by a superadmin, and therefore the security model is not violated by this finding.","published":"2022-02-24T15:15:25.000Z","lastModified":"2026-06-17T04:13:01.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-434"],"affected":["limesurvey/limesurvey"],"epss":{"score":0.13502,"percentile":0.96449,"date":"2026-11-03","history":[]},"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 13.5%, higher than 96% of all known CVEs.
