CVE-2025-52834: Homey Theme SQL Injection Vulnerability

CVE-2025-52834 Overview

CVE-2025-52834 is a critical SQL Injection vulnerability discovered in the favethemes Homey WordPress theme. This vulnerability allows unauthenticated attackers to inject malicious SQL commands through the web interface, potentially leading to unauthorized access to the WordPress database, data exfiltration, and compromise of sensitive information stored within the CMS.

Critical Impact

Unauthenticated SQL Injection vulnerability in a WordPress theme enables attackers to extract sensitive database contents, modify data, and potentially escalate to full site compromise without requiring any authentication.

Affected Products

• Homey WordPress Theme versions through 2.4.5
• WordPress installations using the vulnerable Homey theme

Technical Details for CVE-2025-52834

Vulnerability Analysis

This vulnerability stems from improper neutralization of special elements used in SQL commands (CWE-89). The Homey WordPress theme fails to properly sanitize user-supplied input before incorporating it into database queries. This weakness allows attackers to manipulate the intended SQL logic by injecting malicious payloads that alter the query structure.

The vulnerability is exploitable over the network without requiring authentication, making it particularly dangerous for internet-facing WordPress installations. Successful exploitation can lead to unauthorized disclosure of confidential database contents, including user credentials, private posts, and other sensitive information stored in the WordPress database.

Root Cause

The root cause of CVE-2025-52834 is the failure to implement proper input validation and parameterized queries within the Homey theme's codebase. User-supplied data is concatenated directly into SQL statements without adequate sanitization or the use of prepared statements, allowing attackers to inject arbitrary SQL syntax. This violates secure coding practices that mandate treating all user input as untrusted and using parameterized queries or stored procedures to prevent SQL injection attacks.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads targeting vulnerable parameters within the Homey theme functionality. The injected SQL code is then executed by the database server with the privileges of the WordPress database user.

Common exploitation techniques include UNION-based injection to extract data from other tables, Boolean-based blind injection to infer database contents through true/false responses, and time-based blind injection using database sleep functions. Attackers may leverage these techniques to enumerate database structure, extract user credentials, access private content, or potentially achieve further compromise depending on database permissions.

Detection Methods for CVE-2025-52834

Indicators of Compromise

• Unusual database queries in MySQL/MariaDB logs containing SQL syntax anomalies such as UNION SELECT, OR 1=1, or encoded payloads
• Web server access logs showing requests with SQL injection patterns in query parameters
• Unexpected database errors or verbose SQL error messages appearing in application logs
• Evidence of data exfiltration or unauthorized database access in audit logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting WordPress themes
• Implement database activity monitoring to identify anomalous query patterns or unauthorized data access
• Configure intrusion detection systems (IDS) with signatures for SQL injection attack patterns
• Enable WordPress audit logging to track suspicious activity related to theme functionality

Monitoring Recommendations

• Monitor web server logs for requests containing SQL injection indicators such as single quotes, double dashes, or SQL keywords in unexpected parameters
• Configure alerting for database query failures or unusual execution patterns
• Implement real-time monitoring of WordPress file integrity to detect any unauthorized modifications following potential exploitation
• Review database access logs for evidence of bulk data extraction or privilege escalation attempts

How to Mitigate CVE-2025-52834

Immediate Actions Required

• Update the Homey WordPress theme to a patched version beyond 2.4.5 if available from favethemes
• If no patch is available, consider temporarily disabling or removing the Homey theme until a fix is released
• Implement WAF rules to block SQL injection attempts targeting WordPress installations
• Review database logs for any indicators of prior exploitation and assess potential data exposure
• Rotate database credentials if compromise is suspected

Patch Information

Organizations should monitor favethemes for security updates addressing this SQL injection vulnerability. The Patchstack advisory provides additional details on the vulnerability and remediation guidance. Apply any available updates as soon as they are released by the vendor.

Workarounds

• Deploy a Web Application Firewall with SQL injection detection rules to filter malicious requests before they reach the application
• Implement network-level access controls to restrict access to WordPress administrative functions from trusted IP addresses only
• Consider using WordPress security plugins that provide virtual patching capabilities for known theme vulnerabilities
• Temporarily switch to an alternative WordPress theme if the Homey theme is not critical to operations
