CVE-2026-54175backpack/crud: Unverified password change in MyAccountController via mass assignment

backpack/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.
