Technical description

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the OAuth2 authentication module updates an existing local account with profile attributes that can include userPassword and inetUserStatus, rewriting the password to the username and reactivating disabled accounts. The missing OAuth.removeRestrictedAccountUpdateAttributes filtering permits these credential and status fields to reach the account update. With account creation enabled, repeated OAuth login causes the default ldapService chain to accept the username as both identifier and password, allowing an unauthenticated attacker to take over the local account without interacting with the identity provider. The rewrite can be denied for usernames shorter than the configured minimum password length. This issue is fixed in version 16.1.1.

———zlt2000 microservices-platform through 6.0.0 contains an unverified password change vulnerability in the PUT /users/password endpoint that allows authenticated users to change any account password by omitting the current password check. Attackers can supply an arbitrary user id in the request body and a new password to overwrite credentials of any non-administrator account without verification.8h CVE-2026-919959.1 CRI

——0pig before 4.1.0 contains an authentication bypass vulnerability in the /register/password endpoint where password verification results are discarded, allowing any value as the current password. Remote attackers can submit a username with an incorrect current password to overwrite any account credential including the admin account and gain full administrative control.1d CVE-2026-541766.5 MED

——12backpack/crud provides Create, Read, Update & Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. From 6.0.0 until 6.8.14 and 7.0.38, MyAccountController::postAccountInfoForm at POST /admin/edit-account-info permits AccountInfoRequest to update backpack_authentication_column(), which is email by default, without requiring current_password or otherwise verifying the account's existing password. An attacker with a temporary authenticated Backpack session can change the account-recovery email and later use the password-reset flow after the original session expires, converting session compromise into persistent account takeover. The same mechanism permits an insider to set a personal recovery address before access is revoked. The separate password-change endpoint is not affected because it verifies old_password. This issue is fixed in versions 6.8.14 and 7.0.38.2d CVE-2026-541757.6 HIG

——10backpack/crud provides Create, Read, Update & Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. Prior to 6.8.11 and 7.0.34, MyAccountController::postAccountInfoForm in src/app/Http/Controllers/MyAccountController.php at POST /admin/edit-account-info passes request data from $request->except(['_token']) to the user model instead of restricting updates to fields accepted by AccountInfoRequest::validationData(). An attacker with an authenticated Backpack session can therefore mass-assign password, the authentication column, or other deployment-specific fillable attributes. With the default Laravel 11 user model, a submitted plaintext password is automatically hashed and persisted, converting temporary session access into persistent account takeover without the old_password check enforced by the separate password-change route. Changing the authentication email can also enable later password-reset takeover, while additional fillable security attributes can permit deployment-specific privilege escalation or security-control changes. This issue is fixed in versions 6.8.11 and 7.0.34.2d CVE-2026-862606.5 MED

——7phpMyFAQ versions before 4.1.8 contain an authentication bypass vulnerability in the user control panel API endpoint that allows authenticated attackers to change account passwords without verifying the current password. Attackers with session access can submit a PUT request to the user data update endpoint with only a CSRF token to silently change any user's password, including administrators, causing irreversible account takeover and victim lockout.6d
