{"id":"CVE-2026-34384","summary":"Admidio: Missing CSRF Protection on Registration Approval Actions","details":"Admidio is an open-source user management solution. Prior to version 5.0.8, the create_user, assign_member, and assign_user action modes in modules/registration.php approve pending user registrations via GET request without validating a CSRF token. Unlike the delete_user mode in the same file (which correctly validates the token), these three approval actions read their parameters from $_GET and perform irreversible state changes without any protection. An attacker who has submitted a pending registration can extract their own user UUID from the registration confirmation email URL, then trick any user with the rol_approve_users right into visiting a crafted URL that automatically approves the registration. This bypasses the manual registration approval workflow entirely. This issue has been patched in version 5.0.8.","aliases":["GHSA-ph84-r98x-2j22"],"modified":"2026-04-10T05:43:01.633425Z","published":"2026-03-31T20:34:37.789Z","database_specific":{"cwe_ids":["CWE-352"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34384.json"},"references":[{"type":"FIX","url":"https://github.com/Admidio/admidio/commit/707171c188b3e8f36007fc3f2bccbfac896ed019"},{"type":"ADVISORY","url":"https://github.com/Admidio/admidio/security/advisories/GHSA-ph84-r98x-2j22"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/34xxx/CVE-2026-34384.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34384"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/admidio/admidio","events":[{"introduced":"0"},{"fixed":"3833691ef1746e92b0e009dace220049caa65806"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"5.0.8"}]}}],"versions":["3.0-Beta.1","3.0-Beta.3","v3.0.6","v3.1.5","v3.2-Beta.1","v34","v4.0-Beta.1","v4.1-Beta.2","v4.3-Beta.1","v5.0-Beta.1","v5.0-Beta.2","v5.0-Beta.3","v5.0.0","v5.0.1","v5.0.2","v5.0.3","v5.0.4","v5.0.5","v5.0.6","v5.0.7"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-34384.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:H/A:N"}]}
