CVE-2026-44585 (GCVE-0-2026-44585)

Vulnerability from cvelistv5 – Published: 2026-07-20 20:04 – Updated: 2026-07-21 12:48

Title

Paymenter: Broken object level authorization via service reference manipulation on ticket creation

Summary

Paymenter is a free and open-source webshop solution for management of hosting services. In versions prior to 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. An attacker could modify the service ID value in the client-side request and successfully create a ticket associated with another user's service. The vulnerability requires authentication and does not provide direct access to service contents or customer data. However, referenced service information could become visible to support personnel handling the ticket. Successful exploitation could allow an authenticated user to: create support tickets referencing services belonging to other users, potentially cause support staff to interact with or review unrelated customer services. The vulnerability did not allow direct access to another user's service, modification of another user's service or retrieval of confidential service data through the vulnerable endpoint itself. This issue has been fixed in version 1.5.0.

GHSA-X93Q-X9PC-W5HW

Vulnerability from github – Published: 2026-06-22 20:30 – Updated: 2026-06-22 20:30

Summary

Paymenter has broken object level authorization via service reference manipulation on ticket creation

Details

Summary

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.

Technical Details

The ticket creation endpoint accepted a user-supplied service identifier without verifying ownership or authorization against the authenticated account. An attacker could modify the service ID value in the client-side request and successfully create a ticket associated with another user's service.

The vulnerability required authentication and did not provide direct access to service contents or customer data. However, referenced service information could become visible to support personnel handling the ticket.

Impact

Successful exploitation could allow an authenticated user to: - Create support tickets referencing services belonging to other users - Potentially cause support staff to interact with or review unrelated customer services

The vulnerability did not allow: - Direct access to another user's service - Modification of another user's service - Retrieval of confidential service data through the vulnerable endpoint itself

Severity

5.4 (Medium)

  "details": "### Summary\nThe 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.\n\n### Technical Details\n\nThe ticket creation endpoint accepted a user-supplied service identifier without verifying ownership or authorization against the authenticated account. An attacker could modify the service ID value in the client-side request and successfully create a ticket associated with another user\u0027s service.\n\nThe vulnerability required authentication and did not provide direct access to service contents or customer data. However, referenced service information could become visible to support personnel handling the ticket.\n\n### Impact\n\nSuccessful exploitation could allow an authenticated user to:\n- Create support tickets referencing services belonging to other users\n- Potentially cause support staff to interact with or review unrelated customer services\n\nThe vulnerability did not allow:\n- Direct access to another user\u0027s service\n- Modification of another user\u0027s service\n- Retrieval of confidential service data through the vulnerable endpoint itself",
