backpack/crudbackpack/crudSummary
MyAccountController::postAccountInfoForm allows an authenticated user to update
the authentication column (default: email) without verifying their current password.
Because email is the account-recovery anchor, this enables account takeover after
the attacker's session ends: the new email address can be used to request a password
reset from outside the system.
The password-change endpoint in the same controller correctly requires old_password
verification, so the gap is asymmetric.
Details
The postAccountInfoForm action passes $request->validated() directly to
$user->update(). The AccountInfoRequest whitelists the authentication column
(email by default) with no ownership challenge. Contrast this with
ChangePasswordRequest, which uses Hash::check against the stored password before
allowing any change.
Scenarios where this is exploitable include:
- A brief unauthorized session (e.g. unattended workstation, XSS in the admin panel)
- An insider/offboarding case where a departing admin sets a personal email address before access is revoked, then resets the password after leaving
Patch
Fixed in #5990 — the
authentication column is now protected by a current_password check (mirroring
ChangePasswordRequest) whenever its value changes.
A stronger mitigation — sending a verification link to the new address before
persisting the change — can be layered on top using Laravel's MustVerifyEmail flow.
