SCA: security update for paymenter/paymenter (GHSA-pgcq-8grm-5rx9)

medium Tenable Cloud Security Plugin ID 444134

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Paymenter is a free and open-source webshop solution for management of hosting services. In versions prior
 to 1.5.5, the credit payment implementation in app/Livewire/Invoices/Show.php executes a pessimistic row
 lock (lockForUpdate()) outside of an active database transaction. Because MySQL/MariaDB requires an
 enclosing transaction to enforce row-level locks, the guard is ineffective. Concurrent payment requests
 can exploit this race condition to read the same credit balance simultaneously, allowing users to pay
 multiple invoices using the same credit balance. In database systems like MySQL, a row lock only works
 inside a formal transaction; without one, the lock is completely ignored. Because there is no active lock,
 two payment requests sent at the exact same millisecond can look at the database at the same time. Both
 requests see the original credit balance, decide it is sufficient, and approve the payment. Because the
 payment processes successfully through ExtensionHelper::addPayment(), the application provisions the
 corresponding services or digital goods, resulting in direct financial or resource loss to the platform.
 This issue has been fixed in version 1.5.5. (CVE-2026-55219)

Solution

Update the paymenter/paymenter library and its related packages to version 1.5.5 or later.
