The Gym Management System version 1.0 contains an SQL injection vulnerability in the /admin/edit_exercises.php endpoint. Specifically, the edit_exercise parameter is not properly sanitized, allowing an attacker with high privileges to inject SQL commands remotely. This vulnerability has a CVSS 4.0 base score of 5.1, indicating medium severity. Although the exploit is public, there is no vendor-provided patch or official remediation at this time.

Successful exploitation of this vulnerability could allow an attacker with high privileges to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data access or modification. The impact is limited by the requirement for high privileges and the vulnerability's low vector complexity and low confidentiality, integrity, and availability impacts as per the CVSS vector.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, it is recommended to restrict access to the affected functionality to trusted users only and consider implementing web application firewall rules to detect and block SQL injection attempts targeting the edit_exercise parameter.
