{"id":"CVE-2026-47228","aliases":["GHSA-mx25-j3rc-6w2w"],"url":"https://o3.security/vulnerability/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.","published":"2026-08-12T13:09:18.463Z","modified":"2026-08-14T03:51:53.408772135Z","cvss":{"score":5.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:H/A:L"},"epss":{"score":0.00108,"percentile":0.01397,"asOf":"2026-08-20"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"admidio/admidio","fixedVersion":"5.0.10"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T03:51:53.408772135Z"}}
