CVE-2026-47231

Admidio has IDOR in `documents-files.php` `mode=move_save` that lets any folder-uploader exfiltrate files from private folders

Admidio is an open-source user management solution. Prior to version 5.0.10, `modules/documents-files.php` gates state-changing modes by checking that the actor has `hasUploadRight()` on the URL parameter `folder_uuid`. The `move_save` handler then 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 containing the file. As a result, any user who can upload to any single folder can move any file from any other folder — including private folders to which they have no view rights — into a folder they control, and then download it. Confidentiality is broken (private file contents leak) and integrity is broken (the file is removed from the original location). Version 5.0.10 contains a fix.

CVE-2026-47232

Admidio PKCS#12 private key export action lacks CSRF protection

Admidio is an open-source user management solution. Prior to version 5.0.10, the sensitive `mode=export` action in `modules/sso/keys.php` exports a PKCS#12 bundle containing the configured private key and certificate, but the CSRF validation line is commented out. A forged cross-site POST from an administrator session can therefore trigger private key export without a valid form token. Version 5.0.10 contains a fix.

Incomplete fix for CVE-2026-32812: SSRF in admidio

Admidio is an open-source user management solution. Prior to version 5.0.9, the incomplete SSRF fix in Admidio's fetch_metadata.php validates the resolved IP address but passes the original hostname-based URL to curl_init(), leaving a DNS rebinding TOCTOU window that allows redirecting requests to internal IPs. This issue has been patched in version 5.0.9.

Admidio: Hidden Profile Field Values Leaked via Blind Search Oracle in Member Assignment

Admidio is an open-source user management solution. Prior to version 5.0.9, the member assignment DataTables endpoint (members_assignment_data.php) includes hidden profile fields (BIRTHDAY, STREET, CITY, POSTCODE, COUNTRY) in its SQL search condition regardless of field visibility settings. While the JSON output correctly suppresses hidden columns via isVisible() checks, the server-side search operates at the SQL level before any visibility filtering. This allows a role leader with assign-only permissions to infer hidden PII values by observing which users appear in search results for specific values. This issue has been patched in version 5.0.9.

Admidio is an open-source user management solution. Prior to version 5.0.9, an unauthenticated attacker can execute arbitrary JavaScript in any Admidio user's browser through a reflected XSS in system/msg_window.php. The endpoint passes user input through htmlspecialchars(), which does not encode square brackets. A subsequent call to Language::prepareTextPlaceholders() converts those brackets into HTML angle brackets, producing executable markup. This issue has been patched in version 5.0.9.

Admidio: SAML Signature Validation Result Ignored — Forged AuthnRequests and LogoutRequests Processed

Admidio is an open-source user management solution. Prior to version 5.0.9, the Admidio SAML Identity Provider implementation discards the return value of its validateSignature() method at both call sites (handleSSORequest() line 418 and handleSLORequest() line 613). The method returns error strings on failure rather than throwing exceptions, but the developer believed it would throw (per comments on lines 416 and 611). This means the smc_require_auth_signed configuration option is completely ineffective — unsigned or invalidly-signed SAML AuthnRequests and LogoutRequests are processed identically to properly signed ones. This issue has been patched in version 5.0.9.

Admidio: Missing Minimum Administrator Check in Role Membership Removal

Admidio is an open-source user management solution. Prior to version 5.0.9, Role::stopMembership() does not verify whether removing a user from the administrator role leaves zero administrators. The deprecated Membership::stopMembership() contains this safety check, but the current code path bypasses it. Any administrator can remove the last remaining other administrator, locking the entire system out of administrative access. The exploit does not require concurrent requests; sequential removals produce the same result. This issue has been patched in version 5.0.9.

Admidio: Path Traversal via Unvalidated `name` Parameter in Document Add Mode Enables Arbitrary Server File Read

Admidio is an open-source user management solution. Prior to version 5.0.9, the add mode in modules/documents-files.php accepts a name parameter validated only as 'string' type (HTML encoding), allowing path traversal characters (../) to pass through unfiltered. Combined with the absence of CSRF protection on this endpoint and SameSite=Lax session cookies, a low-privileged attacker can trick a documents administrator into clicking a crafted link that registers an arbitrary server file (e.g., install/config.php containing database credentials) into a documents folder accessible to the attacker. This issue has been patched in version 5.0.9.

Admidio: Missing Authorization on Inventory Module Destructive Endpoints Allows Any Authenticated User to Delete Items

Admidio is an open-source user management solution. Prior to version 5.0.9, the Admidio inventory module enforces authorization for destructive operations (delete, retire, reinstate) only in the UI layer by conditionally rendering buttons. The backend POST handlers at modules/inventory.php for item_delete, item_retire, item_reinstate, item_picture_upload, item_picture_save, and item_picture_delete perform CSRF validation but never check whether the requesting user is an inventory administrator. Any authenticated user who can access the inventory module can permanently delete any inventory item and all its associated data. This issue has been patched in version 5.0.9.

Admidio: SAML Response Sent to Unvalidated Assertion Consumer Service URL from AuthnRequest

Admidio is an open-source user management solution. Prior to version 5.0.9, the SAML IdP implementation in Admidio's SSO module uses the AssertionConsumerServiceURL value directly from incoming SAML AuthnRequest messages as the destination for the SAML response, without validating it against the registered ACS URL (smc_acs_url) stored in the database for the corresponding service provider client. An attacker who knows the Entity ID of a registered SP client can craft a SAML AuthnRequest with an arbitrary AssertionConsumerServiceURL, causing the IdP to send the signed SAML response -- containing user identity attributes (login name, email, roles, profile fields) -- to an attacker-controlled URL. This issue has been patched in version 5.0.9.

Admidio: OIDC Token Introspection Endpoint Returns Active for All Tokens Without Validation

Admidio is an open-source user management solution. Prior to version 5.0.9, the OIDC token introspection endpoint (/modules/sso/index.php/oidc/introspect) always returns {"active": true} for every request, regardless of whether a valid token is provided, whether the token is expired, revoked, or completely fabricated. The endpoint performs no authentication of the calling resource server and no validation of the submitted token. Any resource server that relies on this introspection endpoint to validate access tokens will accept all requests as authorized, enabling complete authentication bypass. Additionally, the OIDC token revocation endpoint (/oidc/revoke) returns {"revoked": true} without actually revoking any token, preventing resource servers from invalidating compromised credentials. This issue has been patched in version 5.0.9.

Admidio: Cross-Organization Member Data Exposure via Permission Check Mismatch in contacts_data.php

Admidio is an open-source user management solution. Prior to version 5.0.9, the contacts_data.php endpoint uses a weaker permission check (isAdministratorUsers(), requiring only rol_edit_user=true) than the frontend UI (contacts.php) which correctly requires the stronger isAdministrator() (requiring rol_administrator=true) and the contacts_show_all system setting. A user manager who is not a full administrator can directly request contacts_data.php?mem_show_filter=3 to retrieve all user records across all organizations in the Admidio instance, bypassing multi-tenant organization isolation. This issue has been patched in version 5.0.9.
