CVE-2025-63029: WCFM Marketplace SQL Injection Flaw

CVE-2025-63029 Overview

CVE-2025-63029 is a SQL Injection vulnerability affecting the WCFM Marketplace plugin for WordPress, developed by WC Lovers. This vulnerability allows attackers to inject malicious SQL commands through improperly neutralized special elements in user-supplied input, potentially compromising the underlying database and sensitive information stored within.

Critical Impact

Authenticated attackers with high privileges can exploit this SQL Injection vulnerability to extract sensitive data from the WordPress database, including user credentials, customer information, and marketplace transaction data. The vulnerability has a changed scope, meaning successful exploitation can impact resources beyond the vulnerable component.

Affected Products

• WCFM Marketplace plugin versions through 3.7.1
• WordPress installations running vulnerable WCFM Marketplace versions
• WooCommerce multi-vendor marketplace sites using affected plugin versions

Technical Details for CVE-2025-63029

Vulnerability Analysis

This SQL Injection vulnerability stems from inadequate input sanitization within the WCFM Marketplace plugin. The plugin fails to properly neutralize special characters in user-controlled input before incorporating it into SQL queries. While exploitation requires high-privilege authentication, successful attacks can have cross-scope impact, allowing attackers to access confidential data beyond the vulnerable component's boundaries.

The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), which represents a failure to properly sanitize or validate user input before using it in database queries. This allows attackers to modify the intended SQL query logic, potentially extracting, modifying, or deleting database contents.

Root Cause

The root cause of this vulnerability is insufficient input validation and improper use of parameterized queries or prepared statements within the WCFM Marketplace plugin codebase. User-supplied data is concatenated directly into SQL queries without proper escaping or sanitization of SQL metacharacters such as single quotes, double quotes, and SQL command keywords. This allows attackers to break out of the intended query context and inject arbitrary SQL commands.

Attack Vector

The attack is network-accessible and requires no user interaction, though it does require the attacker to possess high-level privileges within the WordPress installation. An authenticated attacker can craft malicious input containing SQL injection payloads and submit it through vulnerable plugin endpoints. The injected SQL commands are then executed against the database with the privileges of the database user configured for the WordPress installation.

The vulnerability enables high confidentiality impact through unauthorized data extraction, though integrity impact is not present. There is also potential for limited availability impact on database resources. For detailed technical information about the exploitation mechanism, refer to the Patchstack SQL Injection Advisory.

Detection Methods for CVE-2025-63029

Indicators of Compromise

• Unusual database query patterns in WordPress database logs showing SQL injection syntax such as UNION SELECT, OR 1=1, or comment sequences like -- and /*
• Web server access logs containing URL-encoded SQL injection payloads targeting WCFM Marketplace plugin endpoints
• Unexpected database errors or timeout messages in application logs indicating malformed queries
• Evidence of bulk data extraction or abnormal database read operations from privileged user sessions

Detection Strategies

• Deploy Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting WordPress plugin parameters
• Implement database activity monitoring to flag queries containing suspicious SQL injection patterns originating from the WCFM Marketplace plugin
• Review WordPress authentication logs for privileged accounts exhibiting unusual behavior or accessing marketplace functionality abnormally
• Utilize SentinelOne Singularity to monitor for post-exploitation activities and lateral movement following potential database compromise

Monitoring Recommendations

• Enable comprehensive logging for WordPress database queries and review for SQL injection indicators
• Monitor network traffic for exfiltration attempts following potential database compromise
• Configure alerts for bulk data access patterns or unusual read operations on sensitive database tables
• Implement real-time monitoring of privileged user sessions interacting with WCFM Marketplace functionality

How to Mitigate CVE-2025-63029

Immediate Actions Required

• Update WCFM Marketplace plugin to a patched version beyond 3.7.1 as soon as available from the vendor
• Implement WAF rules to block SQL injection attempts targeting the plugin while awaiting a patch
• Review and restrict high-privilege account access to minimize the attack surface
• Audit database access logs for signs of exploitation and rotate database credentials if compromise is suspected

Patch Information

Organizations should update the WCFM Marketplace plugin to the latest available version that addresses this SQL Injection vulnerability. Monitor the official WordPress plugin repository and the Patchstack advisory for patch release announcements. Until a patch is available, implement the workarounds and monitoring recommendations outlined above.

Workarounds

• Deploy a Web Application Firewall with SQL injection detection rules in front of the WordPress installation
• Restrict administrative access to the WordPress site to trusted IP addresses only
• Consider temporarily disabling the WCFM Marketplace plugin if it is not business-critical until a patch is available
• Implement database-level access controls to limit the privileges of the WordPress database user
