CVE-2025-46460: Detheme Easy Guide SQL Injection Flaw

CVE-2025-46460 Overview

CVE-2025-46460 is a SQL Injection vulnerability affecting the Detheme Easy Guide plugin for WordPress. The vulnerability stems from improper neutralization of special elements used in SQL commands, allowing attackers to inject malicious SQL queries. This flaw enables unauthorized database access and manipulation without authentication.

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability to extract sensitive data from WordPress databases, potentially compromising user credentials, personal information, and site configuration data.

Affected Products

• Detheme Easy Guide plugin version 1.0.0 and earlier
• WordPress installations using the wp-easy-guide plugin

Technical Details for CVE-2025-46460

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) in the Detheme Easy Guide WordPress plugin allows attackers to manipulate database queries through unsanitized user input. The vulnerability is exploitable over the network without requiring any authentication or user interaction, and has the potential to impact resources beyond the vulnerable component's scope. Successful exploitation can lead to high confidentiality impact through unauthorized data extraction, while also potentially causing limited availability disruption.

Root Cause

The root cause of this vulnerability is the failure to properly sanitize and validate user-supplied input before incorporating it into SQL queries. The Easy Guide plugin does not implement adequate input neutralization, allowing special SQL characters and commands to be interpreted by the database engine rather than treated as literal data. This is a classic example of improper input validation leading to injection vulnerabilities.

Attack Vector

The attack vector is network-based, requiring no authentication or privileges to exploit. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable parameters in the Easy Guide plugin. These payloads are processed by the WordPress database layer without proper sanitization, allowing the attacker to execute arbitrary SQL commands. The attack can be performed remotely with low complexity, as it does not require user interaction or specialized conditions.

The vulnerability allows attackers to:

• Extract sensitive data from the WordPress database including user credentials
• Enumerate database structure and table contents
• Potentially modify or delete database records depending on database permissions
• Access data from other applications sharing the same database server

Detection Methods for CVE-2025-46460

Indicators of Compromise

• Unusual SQL error messages in WordPress debug logs referencing the Easy Guide plugin
• Suspicious HTTP requests containing SQL syntax characters (', ", ;, --, UNION, SELECT) targeting Easy Guide endpoints
• Abnormal database query patterns or increased database load
• Evidence of unauthorized data access or extraction in database audit logs

Detection Strategies

• Monitor web application firewall (WAF) logs for SQL injection attack patterns targeting /wp-content/plugins/wp-easy-guide/
• Implement database query logging and analyze for suspicious query patterns
• Deploy intrusion detection systems with SQL injection signature detection
• Review WordPress access logs for anomalous requests to Easy Guide plugin endpoints

Monitoring Recommendations

• Enable WordPress debug logging and monitor for SQL-related errors
• Configure database activity monitoring to alert on unusual query patterns
• Set up alerts for repeated failed or malformed database queries
• Monitor for data exfiltration indicators such as large database responses

How to Mitigate CVE-2025-46460

Immediate Actions Required

• Deactivate and remove the Detheme Easy Guide plugin immediately if no patch is available
• Implement web application firewall rules to block SQL injection attempts
• Restrict database user privileges to minimum required permissions
• Review WordPress and database logs for signs of exploitation

Patch Information

As of the publication date, no official patch has been released for this vulnerability. The affected version is Easy Guide 1.0.0 and all prior versions. Website administrators should monitor the Patchstack WordPress Vulnerability Report for updates on remediation guidance and check for plugin updates through the WordPress plugin repository.

Workarounds

• Remove the Easy Guide plugin until a security patch is available
• Implement WAF rules specifically blocking SQL injection patterns for Easy Guide endpoints
• Use database-level query monitoring and blocking for suspicious patterns
• Consider alternative WordPress guide plugins with better security track records

# Disable the Easy Guide plugin via WP-CLI
wp plugin deactivate wp-easy-guide --allow-root

# Verify the plugin is deactivated
wp plugin list --status=inactive --allow-root | grep easy-guide

# Optional: Remove the plugin entirely
wp plugin delete wp-easy-guide --allow-root
