SCA: security update for paymenter/paymenter (GHSA-7wwh-xcc3-9fcg)

medium Tenable Cloud Security Plugin ID 443787

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 1.5.0, the PayPal webhook endpoint /extensions/paypal/webhook processes the PAYPAL-CERT-URL HTTP header
without validation, allowing attackers to control server-side HTTP request destinations. This value is
passed directly into a server-side HTTP request via file_get_contents, allowing attackers to control the
destination of the request. No allowlist, validation, or signature verification is applied to the header
before usage. As a result, the application can be coerced into performing HTTP requests to attacker-
controlled or internal network destinations. This vulnerability allows remote unauthenticated attackers to
induce server-side HTTP GET requests to arbitrary external or internal endpoints. Depending on network
configuration, this may lead to: blind SSRF to external attacker-controlled systems, and potential access
to internal network services No direct response data is returned to the attacker (blind SSRF), but the
issue may still enable sensitive network probing or data exfiltration via side channels. This issue has
been fixed in version 1.5.0. (CVE-2026-44583)

Solution

Update the paymenter/paymenter library and its related packages to version 1.5.0 or later.
