CVE-2025-7442 is a high-severity SQL Injection vulnerability affecting the WPGYM - Wordpress Gym Management System plugin developed by dasinfomedia. This vulnerability exists in all versions up to 67.8.0 of the plugin. The flaw arises due to improper neutralization of special elements used in SQL commands (CWE-89), specifically insufficient escaping and lack of prepared statements for user-supplied parameters in multiple functions: MJ_gmgt_delete_class_limit_for_member, MJ_gmgt_get_yearly_income_expense, MJ_gmgt_get_monthly_income_expense, MJ_gmgt_add_class_limit, MJ_gmgt_view_meeting_detail, and MJ_gmgt_create_meeting. These functions handle various gym management operations such as managing class limits, retrieving financial data, and managing meetings. Because the plugin fails to sanitize inputs properly, unauthenticated attackers can inject malicious SQL code, appending additional queries to extract sensitive data from the backend database. The vulnerability requires no authentication or user interaction and can be exploited remotely over the network. The CVSS 3.1 base score is 7.5, reflecting high impact on confidentiality with no impact on integrity or availability. No known exploits are currently reported in the wild, and no patches have been published yet. The root cause is the absence of parameterized queries or prepared statements, which would otherwise prevent SQL injection by separating code from data. This vulnerability could allow attackers to access sensitive information such as user data, financial records, or other confidential gym management data stored in the database, potentially leading to data breaches and privacy violations.

For European organizations using WordPress websites with the WPGYM plugin, this vulnerability poses a significant risk to the confidentiality of sensitive customer and business data. Gym management systems often store personally identifiable information (PII), membership details, payment records, and scheduling information. Exploitation could lead to unauthorized data disclosure, violating GDPR and other data protection regulations, resulting in legal penalties and reputational damage. Additionally, data leakage could facilitate further attacks such as identity theft or fraud. Since the vulnerability is exploitable without authentication, attackers can target vulnerable sites en masse, increasing the risk of widespread data breaches. The impact is particularly critical for gyms and fitness centers that rely heavily on digital management systems and handle large volumes of member data. The lack of patches means organizations must act quickly to mitigate risk. The vulnerability does not affect system integrity or availability directly but compromises confidentiality, which is a core security principle under European data protection laws.

Immediate mitigation steps include: 1) Temporarily disabling or uninstalling the WPGYM plugin until a secure patched version is released. 2) Employing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the vulnerable plugin’s endpoints. 3) Restricting access to the affected plugin’s functions by IP whitelisting or authentication enforcement at the web server or application level. 4) Conducting thorough input validation and sanitization on all user inputs related to the plugin, if custom code modifications are feasible. 5) Monitoring web server logs for suspicious SQL injection attempts targeting the plugin’s functions. 6) Planning for an update strategy to apply vendor patches promptly once available. 7) Considering isolating the WordPress environment or using containerization to limit the blast radius of a potential compromise. These measures go beyond generic advice by focusing on specific plugin functions and practical interim controls until official patches are available.
