Summary
Admidio prior to version 5.0.8 contains a CSRF vulnerability in the registration module. Approval actions for pending registrations (create_user, assign_member, assign_user) are performed via GET requests without CSRF token validation, allowing an attacker to auto-approve their own registration by tricking an administrator with appropriate rights.
Risk Assessment
An attacker can bypass the manual registration approval process and gain unauthorized access to the system, potentially leading to privilege escalation or data breach.
Recommendation
Update Admidio to version 5.0.8 or later which includes the fix. In the meantime, restrict the rol_approve_users permission to trusted administrators only.
Other vulnerabilities in Admidio
See all- CVE-2026-41660High
Admidio is an open-source user management solution. Prior to version 5.0.9, a logic error in Admidio's two-factor authentication reset inverts the authorization check, allowing non-admin users to remove other users' TOTP configurations, including administrators.
- CVE-2026-53760Medium
Admidio up to version 5.0.11 has a CSRF vulnerability in modules/plugins.php, where plugin installation, uninstallation, and update operations are performed via GET requests without CSRF token validation. An attacker can craft a malicious page that, when visited by an authenticated administrator, triggers arbitrary plugin operations, including uninstallation, which executes DROP TABLE SQL scripts and destroys plugin data.
- CVE-2026-82658Medium
Admidio versions before 5.0.12 contain a broken access control vulnerability in profile_function.php that allows authenticated low-privilege users to read another user's future role memberships. Attackers can bypass profile-level authorization by directly calling the reload_future_memberships endpoint with a victim's user UUID to disclose sensitive membership information.
- CVE-2026-82657High
Admidio before version 5.0.12 fails to enforce login-only module restrictions in RSS feed endpoints for forum and announcements modules. Unauthenticated attackers can retrieve forum topics and announcements by sending GET requests to rss/forum.php or rss/announcements.php, disclosing titles, full post text, author names, and timestamps.
- CVE-2026-82656Low
Admidio before 5.0.12 fails to sanitize album names in the photo ZIP download functionality, allowing authenticated users with album-creation rights to include path traversal segments in archive entry names. This can lead to writing files outside the target directory when recipients extract the archive.
- CVE-2026-82655High
Admidio before version 5.0.12 contains a blind SQL injection vulnerability in the relation_type_list parameter of lists_show.php that allows unauthenticated attackers to execute arbitrary SQL queries. Attackers can bypass authentication by providing a dummy UUID in role_list and inject SQL through relation_type_list to extract database contents including password hashes and user credentials.
- CVE-2026-47234Medium
Admidio is an open-source user management solution. Prior to version 5.0.10, when debug logging is enabled, `Session::setCookie()` logs full cookie values and `Session::start()` logs the current session ID. In a real Admidio deployment this includes both the active session cookie and the persistent auto-login cookie. Anyone with access to the log sink can recover live bearer-style credentials from the logs. Version 5.0.10 contains a fix.
- CVE-2026-47233Medium
Admidio is an open-source user management solution. Version 5.0.9 added a missing `isAdministratorInventory()` gate to `case 'item_delete':` in `modules/inventory.php`. The same fix was not applied to the sibling `case 'field_delete':` handler, which destroys an entire inventory field definition, cascading to every `adm_inventory_item_data` row that referenced that field and every `adm_inventory_field_options` entry. The handler validates only a session-bound CSRF token; there is no `isAdministratorInventory()` check at the controller level, and `Admidio\Inventory\Entity\ItemField::delete()` does not enforce one at the entity level either (unlike its sibling `ItemField::save()`, which does check `$gCurrentUser->isAdministrator()`). Any user who can log in to the site can permanently destroy a non-system inventory field by sending one POST. Version 5.0.10 provides an updated fix.
- CVE-2026-47232Medium
Admidio prior to version 5.0.10 has a CSRF vulnerability in the `mode=export` action in `modules/sso/keys.php`, which exports a PKCS#12 bundle with the private key and certificate. The CSRF validation line is commented out, allowing a forged cross-site POST from an administrator session to trigger private key export without a valid form token.
- CVE-2026-47231High
Admidio before version 5.0.10 has a vulnerability in modules/documents-files.php where state-changing modes are gated by checking hasUploadRight() on the URL parameter folder_uuid, but the move_save handler operates on a separate URL parameter file_uuid and calls File::moveToFolder($destFolderUUID). File::moveToFolder() checks the upload right on the destination folder but never on the source folder. As a result, any user who can upload to any single folder can move any file from any other folder, including private folders, into a folder they control, and then download it.
Original NVD description (English source)
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.
