{"id":"CVE-2026-34384","state":"PUBLISHED","title":"Admidio: Missing CSRF Protection on Registration Approval Actions","description":"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.","publishedAt":"2026-03-31T20:34:37.789Z","updatedAt":"2026-04-01T15:53:47.600Z","severity":{"score":4.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["Admidio admidio"],"affected":[{"vendor":"Admidio","product":"admidio","versions":[{"version":"< 5.0.8","status":"affected"}]}],"references":["https://github.com/Admidio/admidio/security/advisories/GHSA-ph84-r98x-2j22","https://github.com/Admidio/admidio/commit/707171c188b3e8f36007fc3f2bccbfac896ed019"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/34xxx/CVE-2026-34384.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-34384","state":"PUBLISHED","datePublished":"2026-03-31T20:34:37.789Z","dateUpdated":"2026-04-01T15:53:47.600Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-27T13:45:29.619Z"},"containers":{"cna":{"title":"Admidio: Missing CSRF Protection on Registration Approval Actions","descriptions":[{"lang":"en","value":"Admidio is an open-source user management solution.
