{"id":"CVE-2026-47228","summary":"Admidio's CSRF in registration `send_login` mode resets arbitrary user passwords","details":"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.","aliases":["GHSA-mx25-j3rc-6w2w"],"modified":"2026-09-11T03:30:50.872274310Z","published":"2026-08-12T13:09:18.463Z","database_specific":{"cwe_ids":["CWE-352"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47228.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/Admidio/admidio/security/advisories/GHSA-mx25-j3rc-6w2w"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47228.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47228"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/admidio/admidio","events":[{"introduced":"0"},{"fixed":"8f7a2884e9dc9c51968046d9e6cbd6cb8fda46db"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"5.0.10"}],"source":"AFFECTED_FIELD"}}],"versions":["v5.0.9","v5.0.8","v5.0.7","v5.0.6","v5.0.5","v5.0.4","v34","v5.0.3","v5.0.2","v5.0.1","v5.0.0","v5.0-Beta.3","v5.0-Beta.2","v5.0-Beta.1","v4.3-Beta.1","v4.1-Beta.2","v4.0-Beta.1","v3.2-Beta.1","v3.1.5","v3.0.6","3.0-Beta.3","3.0-Beta.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47228.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:H/A:L"}]}
