description

PHPNuxBill through 2025.3.20 has insufficient attempt controls in its customer password-reset flow. An unauthenticated attacker who knows a customer username may repeatedly guess reset codes and take over that customer's account.

mitigation

Add rate limiting and account or reset-flow lockout controls to the password-reset endpoint, and restrict public access to it where feasible. Apply a vendor-provided update when one is released; no fixed version is recorded.
