Summary
Paymenter before version 1.5.0 fails to invalidate the email verification state after an email change. A verified account retains its verified status even after switching to an unverified address. This could lead to abuse of features gated behind verified status.

The organization may face abuse related to false email verification, potentially affecting trust in the system and enabling unauthorized actions.
Recommendation
Update Paymenter to version 1.5.0 or later.
Other vulnerabilities in Paymenter
See all- CVE-2026-55219Medium
Paymenter versions prior to 1.5.5 have a race condition in the credit payment implementation. The row lock (lockForUpdate()) is executed outside an active database transaction, making it ineffective in MySQL/MariaDB. Concurrent payment requests can read the same credit balance and reuse the same funds.
- CVE-2026-47198High
Paymenter before 1.5.1 has a vulnerability in the checkout component allowing authenticated users to inject arbitrary key-value pairs into server provisioning parameters, potentially overriding resource limits without privileges.
- CVE-2026-44585Medium
In Paymenter prior to version 1.5.0, the ticket creation endpoint accepts a user-supplied service identifier without enforcing ownership validation, allowing authenticated users to create support tickets referencing services belonging to other accounts by modifying the service ID in the request.
- CVE-2026-44583Medium
Paymenter is a free open-source webshop solution for 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 without allowlist, validation, or signature verification. The vulnerability allows remote unauthenticated attackers to trigger HTTP GET requests to arbitrary external or internal endpoints, potentially leading to blind SSRF and access to internal network services.
Original NVD description (English source)
Paymenter is a free and open-source webshop solution for management of hosting services. In versions prior to 1.5.0, the email update functionality fails to invalidate the existing verification state when a user changes their email address, allowing a verified account to retain its verified status after switching to an unverified or unowned email address. When a user updated their email address, the system did not reset or revalidate the associated email verification status. As a result, the verification column remained set to “true” even after the email address was changed. Exploitation could potentially result in: misrepresentation of email ownership, bypass of verification-based trust assumptions, and abuse of features gated behind verified status. No direct unauthorized access to other users accounts or data is possible through this issue alone. This issue has been fixed in version 1.5.0.
