{"id":"CVE-2026-47228","state":"PUBLISHED","title":"Admidio's CSRF in registration `send_login` mode resets arbitrary user passwords","description":"Admidio is an open-source user management solution. `modules/registration.php` mode `send_login` regenerates a random password for `user_uuid_assigned`, stores its bcrypt hash in `adm_users.usr_password`, and emails the cleartext to that user. Every other state-changing mode in the same file (`assign_member`, `assign_user`, `delete_user`, `create_user`) calls `SecurityUtils::validateCsrfToken($_POST['adm_csrf_token'])` first; the `send_login` branch does not. Prior to version 5.0.10, page visited by a registration-administrator can issue the request as a top-level navigation, the browser sends the admin's `SameSite=Lax` cookies, and the server resets the chosen user's password without any further interaction from the admin. Version 5.0.10 fixes the issue.","publishedAt":"2026-08-12T13:09:18.463Z","updatedAt":"2026-08-12T13:32:55.509Z","severity":{"score":5.2,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:H/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["Admidio admidio"],"affected":[{"vendor":"Admidio","product":"admidio","versions":[{"version":"< 5.0.10","status":"affected"}]}],"references":["https://github.com/Admidio/admidio/security/advisories/GHSA-mx25-j3rc-6w2w"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/47xxx/CVE-2026-47228.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-47228","state":"PUBLISHED","datePublished":"2026-08-12T13:09:18.463Z","dateUpdated":"2026-08-12T13:32:55.509Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-18T22:25:21.259Z"},"containers":{"cna":{"title":"Admidio's CSRF in registration `send_login` mode resets arbitrary user passwords","descriptions":[{"lang":"en","value":"Admidio is an open-source user management solution. `modules/registration.php` mode `send_login` regenerates a random password for `user_uuid_assigned`, stores its bcrypt hash in `adm_users.usr_password`, and emails the cleartext to that user.
