CVE-2025-32643: WPGYM SQL Injection Vulnerability

CVE-2025-32643 Overview

CVE-2025-32643 is a critical SQL Injection vulnerability affecting the WPGYM WordPress plugin developed by mojoomla. The vulnerability stems from improper neutralization of special elements used in SQL commands, enabling attackers to perform blind SQL injection attacks against vulnerable WordPress installations running WPGYM versions through 65.0.

Critical Impact

Unauthenticated attackers can exploit this blind SQL injection vulnerability to extract sensitive data from the WordPress database, potentially compromising user credentials, personal information, and other confidential data stored within the affected system.

Affected Products

• WPGYM WordPress Plugin versions from n/a through 65.0
• WordPress sites running vulnerable WPGYM installations

Technical Details for CVE-2025-32643

Vulnerability Analysis

This vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), commonly known as SQL Injection. The blind SQL injection variant present in WPGYM allows attackers to infer database information through application responses without directly viewing query results.

The vulnerability exists because user-supplied input is not properly sanitized before being incorporated into SQL queries executed by the plugin. Attackers can craft malicious input containing SQL metacharacters that alter the intended query logic, allowing them to extract data from the underlying database through time-based or boolean-based inference techniques.

The network-accessible nature of this vulnerability means attackers can exploit it remotely without requiring any prior authentication or user interaction, significantly increasing the risk exposure for affected WordPress installations.

Root Cause

The root cause lies in inadequate input validation and sanitization within the WPGYM plugin's data handling routines. The plugin fails to properly escape or parameterize user-controlled input before constructing SQL queries, allowing malicious SQL syntax to be interpreted as part of the query structure rather than as literal data values.

WordPress provides secure database interaction methods such as $wpdb->prepare() that implement parameterized queries. The absence of these security measures in the vulnerable code paths enables SQL injection attacks.

Attack Vector

The attack vector is network-based, requiring no authentication or privileges. An attacker can submit specially crafted HTTP requests to the WordPress site containing SQL injection payloads. The blind nature of this vulnerability means that while query results are not directly returned to the attacker, information can be extracted through observable differences in application behavior.

Blind SQL injection techniques typically involve:

• Boolean-based blind injection: Crafting conditions that cause different application responses based on true/false evaluation of injected queries
• Time-based blind injection: Using SQL functions like SLEEP() to cause deliberate delays, inferring data based on response timing

The vulnerability affects confidentiality with high severity and can cause limited availability impact on the affected system. For detailed technical analysis, refer to the Patchstack SQL Injection Report.

Detection Methods for CVE-2025-32643

Indicators of Compromise

• Unusual or malformed HTTP requests to WPGYM plugin endpoints containing SQL syntax characters such as single quotes, UNION, SELECT, SLEEP(), or BENCHMARK()
• Database query logs showing abnormal execution times indicating time-based injection attempts
• Web server logs containing URL-encoded SQL injection payloads targeting gym-management plugin paths
• Unexpected database connection spikes or query execution patterns

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in request parameters
• Enable detailed logging for WordPress database queries and monitor for suspicious query structures
• Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns
• Utilize SentinelOne Singularity platform for real-time endpoint monitoring and behavioral analysis of web application attacks

Monitoring Recommendations

• Monitor WordPress access logs for requests containing SQL metacharacters directed at WPGYM plugin routes
• Configure alerting for database queries with unusual execution times or error conditions
• Implement real-time security monitoring using SentinelOne to detect exploitation attempts and malicious activity patterns
• Regularly audit plugin installations and versions across WordPress deployments

How to Mitigate CVE-2025-32643

Immediate Actions Required

• Identify all WordPress installations running WPGYM plugin versions through 65.0 and prioritize them for immediate remediation
• If a patch is not yet available, consider temporarily disabling the WPGYM plugin until a security update is released
• Implement WAF rules to block SQL injection attempts targeting the affected plugin
• Review database access logs for signs of prior exploitation

Patch Information

Consult the Patchstack vulnerability database for the latest patch availability and update instructions from the mojoomla vendor. Update to a patched version as soon as one becomes available.

Workarounds

• Deploy a Web Application Firewall (WAF) with SQL injection protection rules as an interim defense layer
• Restrict access to WordPress administrative and plugin endpoints using IP-based access controls where feasible
• Consider implementing WordPress security plugins that provide additional input validation and query protection
• Temporarily disable the WPGYM plugin if gym management functionality is not critical to operations

# Example: Disable WPGYM plugin via WP-CLI as temporary mitigation
wp plugin deactivate gym-management --path=/var/www/html/wordpress

# Verify plugin status
wp plugin list --path=/var/www/html/wordpress | grep gym-management
