CVE-2025-7049 identifies a critical authorization bypass vulnerability in the WPGYM - Wordpress Gym Management System plugin, versions up to and including 67.7.0. The vulnerability stems from the 'MJ_gmgt_gmgt_add_user' function, which fails to properly validate a user-controlled key parameter. This lack of validation allows authenticated users with minimal privileges (Subscriber-level or higher) to escalate their privileges by altering sensitive user account information such as email addresses and passwords. The vulnerability is classified under CWE-639 (Authorization Bypass Through User-Controlled Key), indicating that the system trusts user input for authorization decisions without adequate verification. The CVSS v3.1 score of 8.8 reflects the vulnerability's high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, and no user interaction required. Exploitation can result in complete account takeover, including administrator accounts, enabling attackers to control the WordPress site, manipulate data, and potentially deploy further malicious activities. Although no known exploits are currently in the wild, the vulnerability's characteristics make it a prime target for attackers. The plugin is widely used in gym management contexts, making affected sites vulnerable until patches or mitigations are applied.

The impact of CVE-2025-7049 is severe for organizations using the WPGYM plugin. Attackers with minimal authenticated access can escalate privileges to administrator level, leading to full site compromise. This includes unauthorized access to sensitive user data, modification or deletion of content, and potential deployment of malware or ransomware. The breach of administrator accounts undermines the integrity and availability of the WordPress site, potentially disrupting business operations, damaging reputation, and causing financial losses. For gym management businesses, this could mean exposure of client personal and payment information, violating privacy regulations and eroding customer trust. The vulnerability's network accessibility and lack of user interaction requirements increase the risk of widespread exploitation. Organizations globally relying on this plugin are at risk until the vulnerability is remediated.

To mitigate CVE-2025-7049, organizations should immediately upgrade the WPGYM plugin to a patched version once released by dasinfomedia. Until an official patch is available, administrators should restrict plugin access to trusted users only and consider disabling the plugin if feasible. Implementing strict role-based access controls in WordPress to limit Subscriber-level users' capabilities can reduce exploitation risk. Monitoring logs for unusual user modification activities and setting up alerts for changes to administrator accounts can help detect exploitation attempts early. Employing Web Application Firewalls (WAFs) with custom rules to block suspicious requests targeting the vulnerable function may provide temporary protection. Regular backups of WordPress sites and databases should be maintained to enable recovery in case of compromise. Additionally, educating users about the risks and enforcing strong authentication mechanisms can further reduce attack surface.
