CVE-2026-4562 Details
Description
A security flaw has been discovered in MacCMS 2025.1000.4052. This affects an unknown part of the file application/api/controller/Timming.php of the component Timming API Endpoint. The manipulation results in missing authentication. The attack may be performed from remote. The exploit has been released to the public and may be used for attacks.
A missing authentication vulnerability has been identified in MacCMS version 2025.1000.4052, specifically within the Timming API endpoint. The issue arises in the file application/api/controller/Timming.php, where the backend authentication check is bypassed, allowing unauthenticated remote attackers to execute scheduled tasks through the public API. This exploitation can trigger various administrative operations, depending on the tasks configured in the backend.
It is recommended to remove the authentication bypass in the Timming API endpoint and implement strong authentication measures, such as HMAC signature authentication or a fixed source IP whitelist. Additionally, backend tasks should not be directly exposed through public APIs without proper authentication and permission checks.
