CVE-2025-47569: WooCommerce Gift Card SQL Injection Flaw

CVE-2025-47569 Overview

A critical SQL Injection vulnerability has been identified in the WPSwings WooCommerce Ultimate Gift Card plugin for WordPress. This vulnerability allows attackers to manipulate SQL queries through improper neutralization of special elements, potentially leading to unauthorized data access and database compromise. The vulnerability affects all versions of the plugin from the initial release through version 2.8.10.

Critical Impact

Unauthenticated attackers can exploit this SQL Injection flaw to extract sensitive data from WordPress databases, including customer information, order details, and potentially administrative credentials.

Affected Products

• WooCommerce Ultimate Gift Card - Create, Sell and Manage Gift Cards with Customized Email Templates (versions through 2.8.10)
• WordPress installations running the vulnerable plugin versions
• WooCommerce stores utilizing gift card functionality

Technical Details for CVE-2025-47569

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) exists due to improper neutralization of special elements used in SQL commands within the WooCommerce Ultimate Gift Card plugin. The flaw allows attackers to inject malicious SQL statements through user-controllable input fields that are not properly sanitized before being incorporated into database queries.

The vulnerability is particularly dangerous because it can be exploited remotely over the network without requiring any authentication or user interaction. Successful exploitation could allow attackers to read sensitive information from the database, including customer personal data, payment information, and administrative credentials. Additionally, the vulnerability scope extends beyond the vulnerable component itself, potentially affecting other parts of the WordPress installation.

Root Cause

The root cause of this vulnerability lies in insufficient input validation and the lack of proper parameterized queries or prepared statements in the plugin's code. User-supplied input is directly concatenated into SQL queries without adequate sanitization, allowing attackers to break out of the intended query structure and execute arbitrary SQL commands.

This is a common vulnerability pattern in WordPress plugins where developers fail to use the $wpdb->prepare() method or equivalent safe query construction techniques when handling dynamic user input in database operations.

Attack Vector

The attack can be executed remotely over the network by any unauthenticated attacker. The exploitation requires no user interaction and can be performed with low complexity. An attacker would craft malicious input containing SQL metacharacters and injection payloads, submitting them through the plugin's vulnerable endpoints.

Typical attack scenarios include:

• Using UNION-based injection to extract data from other database tables
• Employing time-based blind SQL injection to enumerate database contents
• Leveraging error-based injection to reveal database structure information
• Potentially escalating to write operations depending on database permissions

Detection Methods for CVE-2025-47569

Indicators of Compromise

• Unusual database query patterns in web server or database logs containing SQL syntax such as UNION SELECT, OR 1=1, or -- comment sequences
• Error messages in logs revealing database structure or query information
• Unexpected data exfiltration or large database query responses
• Suspicious HTTP requests to gift card-related plugin endpoints with encoded special characters

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting WordPress plugins
• Monitor database query logs for anomalous patterns, especially involving the gift card plugin's database tables
• Deploy intrusion detection systems (IDS) with signatures for SQL injection attacks
• Enable verbose logging on WordPress and analyze requests to the WooCommerce Ultimate Gift Card plugin endpoints

Monitoring Recommendations

• Set up alerts for database errors that may indicate SQL injection attempts
• Monitor for unusual outbound data transfers that could indicate data exfiltration
• Implement real-time log analysis for requests containing SQL metacharacters
• Review access logs regularly for requests to vulnerable plugin endpoints with suspicious query parameters

How to Mitigate CVE-2025-47569

Immediate Actions Required

• Update the WooCommerce Ultimate Gift Card plugin to a patched version immediately if available
• Temporarily disable the plugin if an update is not yet available and the functionality is not critical
• Implement WAF rules to block SQL injection attempts targeting the affected endpoints
• Review database logs for evidence of prior exploitation attempts
• Conduct a security audit of the WordPress installation and associated databases

Patch Information

Organizations should monitor the official WPSwings plugin repository and the WordPress plugin directory for security updates addressing this vulnerability. The Patchstack Vulnerability Report provides additional details on the vulnerability and remediation guidance.

Workarounds

• Deploy a Web Application Firewall with SQL injection protection rules enabled
• Restrict access to the WordPress admin and plugin endpoints to trusted IP addresses where possible
• Implement additional input validation at the web server level using ModSecurity or similar tools
• Consider temporarily removing the plugin until a patch is available if the risk is unacceptable
