CVE-2025-22728: Workreap Theme Plugin SQLi Vulnerability

CVE-2025-22728 Overview

CVE-2025-22728 is a critical SQL Injection vulnerability affecting the AmentoTech Workreap theme's plugin for WordPress. This vulnerability allows attackers to inject malicious SQL commands through improperly neutralized user input, potentially leading to unauthorized database access, data exfiltration, and complete compromise of affected WordPress installations.

Critical Impact

This unauthenticated SQL Injection vulnerability enables remote attackers to execute arbitrary SQL commands against the WordPress database without requiring authentication, potentially exposing sensitive user data, credentials, and enabling full site takeover.

Affected Products

• AmentoTech Workreap (theme's plugin) versions up to and including 3.3.6
• WordPress installations utilizing the Workreap plugin
• Sites using Workreap theme functionality for freelance marketplace features

Technical Details for CVE-2025-22728

Vulnerability Analysis

This vulnerability falls under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), commonly known as SQL Injection. The Workreap plugin fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows unauthenticated attackers to manipulate database queries by injecting malicious SQL statements through vulnerable parameters.

WordPress plugins that interact with the database must implement proper input validation and parameterized queries to prevent SQL injection attacks. The Workreap plugin's failure to implement these security controls exposes the underlying database to direct manipulation by attackers.

Root Cause

The root cause of this vulnerability lies in the improper neutralization of special characters within user-controlled input before it is used in SQL query construction. The affected plugin code directly concatenates user input into SQL statements without adequate sanitization or use of prepared statements with parameterized queries.

When user input containing SQL metacharacters (such as single quotes, double quotes, semicolons, or SQL keywords) is not properly escaped or parameterized, attackers can break out of the intended query context and inject their own SQL commands. This is a fundamental secure coding failure that WordPress plugins should address through the use of the $wpdb->prepare() function.

Attack Vector

The attack can be executed remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable parameters within the Workreap plugin. These payloads can be designed to:

• Extract sensitive data from the WordPress database including user credentials, emails, and personal information
• Modify or delete database records
• Bypass authentication mechanisms
• Potentially escalate to remote code execution through database-specific features like INTO OUTFILE or stored procedures

The vulnerability is particularly dangerous because WordPress freelance marketplace plugins like Workreap typically store sensitive financial and personal data, making them high-value targets for attackers.

Detection Methods for CVE-2025-22728

Indicators of Compromise

• Unusual database query patterns or errors in WordPress debug logs indicating SQL syntax errors
• Unexpected database access patterns or large data transfers from the WordPress database
• Modified or deleted database records without corresponding legitimate user actions
• Presence of new administrator accounts or modified user privileges
• Web server access logs containing SQL injection payloads in request parameters (e.g., UNION SELECT, OR 1=1, encoded SQL characters)

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting WordPress plugins
• Implement database activity monitoring to alert on unusual query patterns, especially those accessing sensitive tables
• Review web server access logs for requests containing SQL metacharacters or common injection signatures
• Monitor WordPress debug logs for database query errors that may indicate injection attempts
• Use intrusion detection systems with signatures for SQL injection attack patterns

Monitoring Recommendations

• Enable comprehensive logging for all HTTP requests to WordPress endpoints associated with the Workreap plugin
• Configure database audit logging to track all queries executed against the WordPress database
• Set up alerts for failed login attempts or privilege escalation activities that may follow successful SQL injection
• Monitor outbound network traffic from the database server for potential data exfiltration

How to Mitigate CVE-2025-22728

Immediate Actions Required

• Update the Workreap plugin to a patched version if available from the vendor
• If no patch is available, consider temporarily deactivating the Workreap plugin until a fix is released
• Implement Web Application Firewall rules to filter SQL injection attempts
• Review database for any signs of compromise or unauthorized modifications
• Rotate database credentials and WordPress administrator passwords as a precautionary measure

Patch Information

Organizations should monitor the Patchstack Vulnerability Database Entry for updates on patch availability from AmentoTech. Given the critical severity of this vulnerability, applying the vendor patch should be prioritized immediately upon release. Versions 3.3.6 and earlier are confirmed vulnerable.

Workarounds

• Deploy a Web Application Firewall (WAF) with SQL injection protection rules enabled for all WordPress endpoints
• Implement IP-based access restrictions to limit who can access administrative and AJAX endpoints used by the Workreap plugin
• Apply the principle of least privilege to the WordPress database user, restricting permissions to only those required for normal operation
• Consider using a WordPress security plugin that provides real-time protection against SQL injection attacks
• If possible, isolate the WordPress installation on a separate network segment to limit potential lateral movement
