CVE-2025-48281: MyStyle Custom Product Designer SQLi Flaw

CVE-2025-48281 Overview

CVE-2025-48281 is a critical SQL Injection vulnerability affecting the MyStyle Custom Product Designer WordPress plugin. This vulnerability allows unauthenticated attackers to execute Blind SQL Injection attacks against vulnerable installations, potentially compromising the confidentiality of sensitive database information stored within the WordPress environment.

The vulnerability stems from improper neutralization of special elements used in SQL commands (CWE-89), enabling malicious actors to manipulate database queries without requiring any authentication or user interaction.

Critical Impact
Unauthenticated attackers can extract sensitive database contents including user credentials, customer data, and other confidential information through Blind SQL Injection techniques.

Affected Products

MyStyle Custom Product Designer plugin versions up to and including 3.21.1
WordPress installations running vulnerable versions of the plugin
WooCommerce stores utilizing the custom product designer functionality

Technical Details for CVE-2025-48281

Vulnerability Analysis

This Blind SQL Injection vulnerability exists within the MyStyle Custom Product Designer plugin, a WordPress extension that provides custom product design capabilities for WooCommerce stores. The vulnerability allows attackers to inject malicious SQL code that is executed by the underlying database without proper sanitization or parameterization.

Blind SQL Injection differs from traditional SQL Injection in that the attacker cannot directly see the results of their injected queries. Instead, they must infer information based on the application's behavior—typically through boolean-based conditions or time-based delays. This makes the vulnerability particularly dangerous as it can be exploited silently without obvious signs of intrusion.

The network-accessible attack vector combined with no authentication requirements and zero user interaction needed makes this vulnerability highly exploitable in real-world scenarios. Successful exploitation could lead to complete database disclosure, potentially exposing WordPress user credentials, customer personal information, order details, and payment-related data stored in the database.

Root Cause

The root cause of this vulnerability is insufficient input validation and improper handling of user-supplied data within SQL query construction. The plugin fails to properly sanitize, validate, or parameterize user input before incorporating it into database queries, allowing specially crafted input to modify the intended SQL command structure.

WordPress plugins that directly concatenate user input into SQL queries rather than using prepared statements with parameterized queries are susceptible to this class of vulnerability. The lack of proper input neutralization enables attackers to escape the intended query context and execute arbitrary SQL statements.

Attack Vector

The vulnerability is exploitable over the network without requiring authentication or user interaction. An attacker can craft malicious HTTP requests targeting vulnerable plugin endpoints, injecting SQL payloads designed to extract database information through boolean-based or time-based inference techniques.

In a typical Blind SQL Injection attack scenario, the attacker would send carefully crafted requests containing SQL injection payloads. By analyzing response times or behavioral differences, the attacker can systematically extract database contents character by character, eventually reconstructing sensitive information such as usernames, password hashes, and other confidential data.

Detection Methods for CVE-2025-48281

Indicators of Compromise

Unusual database query patterns or errors in WordPress/MySQL logs
HTTP requests containing SQL syntax characters such as single quotes, UNION statements, or time-delay functions (e.g., SLEEP(), BENCHMARK())
Abnormally slow response times on plugin endpoints that could indicate time-based SQL injection probing
Unexpected database connections or query execution patterns from web application processes

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block SQL injection payloads targeting WordPress plugin endpoints
Monitor access logs for requests containing common SQL injection patterns such as ' OR '1'='1, UNION SELECT, or encoded SQL syntax
Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns
Enable WordPress debug logging to capture and analyze unusual database query behavior

Monitoring Recommendations

Configure real-time alerting for database errors that may indicate injection attempts
Implement log aggregation and SIEM integration to correlate potential attack patterns across multiple requests
Monitor for reconnaissance activities targeting WordPress plugin enumeration endpoints
Establish baseline database query performance metrics to detect anomalous time-based injection probing

How to Mitigate CVE-2025-48281

Immediate Actions Required

Update the MyStyle Custom Product Designer plugin to a patched version (above 3.21.1) immediately
If an update is not yet available, consider temporarily disabling the plugin until a security patch is released
Review database access logs for signs of exploitation and potential data exfiltration
Consider implementing a Web Application Firewall with SQL injection protection rules

Patch Information

Organizations should monitor the official MyStyle Custom Product Designer plugin page and the Patchstack vulnerability database for patch availability. Update to the latest available version that addresses this SQL injection vulnerability as soon as a fix is released.

Workarounds

Deploy a Web Application Firewall (WAF) with SQL injection protection rules to filter malicious requests before they reach the application
Implement network-level access controls to restrict access to WordPress admin and plugin endpoints from trusted IP addresses only
Temporarily disable the MyStyle Custom Product Designer plugin if it is not critical to business operations
Enable WordPress database query logging and monitoring to detect exploitation attempts

bash

# WordPress configuration - Enable database query logging for monitoring
# Add to wp-config.php before "That's all, stop editing!"
define('SAVEQUERIES', true);

# Consider adding security headers and restricting plugin access via .htaccess
# Example: Block direct access to plugin files
# <FilesMatch "\.php$">
#   Require all denied
# </FilesMatch>
