CVE-2025-68999: Happy Addons for Elementor SQLi Vulnerability

CVE-2025-68999 Overview

CVE-2025-68999 is a Blind SQL Injection vulnerability affecting the Happy Addons for Elementor WordPress plugin. The vulnerability stems from improper neutralization of special elements used in SQL commands (CWE-89), allowing attackers to manipulate database queries through malicious input. This vulnerability affects all versions of the plugin up to and including version 3.20.4.

Critical Impact

Attackers can exploit this Blind SQL Injection vulnerability to extract sensitive data from the WordPress database, including user credentials, personal information, and site configuration data. Successful exploitation could lead to complete database compromise and potentially full site takeover.

Affected Products

• Happy Addons for Elementor (happy-elementor-addons) versions through 3.20.4
• WordPress installations using vulnerable versions of Happy Addons for Elementor
• Sites with Elementor page builder utilizing the Happy Addons extension

Technical Details for CVE-2025-68999

Vulnerability Analysis

This vulnerability is classified as a Blind SQL Injection, meaning attackers cannot directly view the results of their injected queries through the application's normal output. Instead, exploitation relies on observing differences in application behavior—such as response times (time-based blind SQLi) or conditional responses (boolean-based blind SQLi)—to infer database contents character by character.

The Happy Addons for Elementor plugin, developed by HappyMonster, extends the Elementor page builder with additional widgets and features for WordPress sites. The vulnerable code path fails to properly sanitize user-supplied input before incorporating it into SQL queries, creating an injection point that can be exploited by authenticated or unauthenticated attackers depending on the specific vulnerable endpoint.

Root Cause

The root cause of CVE-2025-68999 lies in insufficient input validation and improper use of parameterized queries within the plugin's codebase. User-controlled data is concatenated directly into SQL statements without proper escaping or prepared statement bindings. WordPress provides the $wpdb->prepare() method specifically to prevent SQL injection, but this security control was not properly implemented in the affected functionality.

Attack Vector

Exploitation of this Blind SQL Injection vulnerability typically involves an attacker crafting specially formatted HTTP requests containing SQL metacharacters and injection payloads. Due to the blind nature of this vulnerability, attackers would use automated tools like SQLMap to systematically extract database information through boolean-based or time-based inference techniques.

The attack may target form inputs, AJAX endpoints, or URL parameters processed by the vulnerable Happy Addons widget functionality. Without seeing direct query output, attackers rely on timing delays (using SQL SLEEP() or BENCHMARK() functions) or conditional logic (using AND 1=1 vs AND 1=2 constructs) to determine query success.

Detection Methods for CVE-2025-68999

Indicators of Compromise

• Unusual database query patterns or errors in WordPress debug logs indicating SQL syntax errors
• Abnormally slow page load times potentially indicating time-based SQL injection exploitation
• Unexpected outbound connections from the database server to external hosts
• Modified database records or newly created admin user accounts
• Web server access logs containing SQL injection payloads with SQLi keywords (UNION, SELECT, SLEEP, BENCHMARK)

Detection Strategies

• Deploy Web Application Firewall (WAF) rules specifically targeting SQL injection patterns in requests to WordPress AJAX endpoints
• Monitor WordPress database query logs for suspicious query patterns including SLEEP(), BENCHMARK(), or UNION SELECT statements
• Implement SentinelOne Singularity XDR for endpoint detection of post-exploitation activities following successful SQL injection
• Regularly audit WordPress user accounts and database tables for unauthorized modifications
• Configure intrusion detection systems to alert on anomalous HTTP request patterns containing SQL metacharacters

Monitoring Recommendations

• Enable WordPress debug logging temporarily to capture potential SQL errors (disable in production after investigation)
• Monitor web server access logs for requests containing encoded SQL injection payloads (%27, %22, %3B)
• Set up alerts for database connection anomalies or unusual query execution times
• Track changes to wp_users and wp_usermeta tables for unauthorized admin account creation

How to Mitigate CVE-2025-68999

Immediate Actions Required

• Update Happy Addons for Elementor plugin to the latest patched version beyond 3.20.4
• Review WordPress database for signs of compromise including unauthorized admin accounts
• Implement a Web Application Firewall to block SQL injection attempts while patching
• Temporarily disable the Happy Addons for Elementor plugin if an immediate update is not possible
• Audit and rotate all WordPress user credentials, particularly administrator accounts

Patch Information

Users should update the Happy Addons for Elementor plugin to the latest available version that addresses this SQL Injection vulnerability. Plugin updates can be applied through the WordPress admin dashboard under Plugins > Installed Plugins, or via WP-CLI using the command wp plugin update happy-elementor-addons. Always create a full site backup before applying updates.

For additional details on this vulnerability and patch status, consult the Patchstack Advisory on SQL Injection.

Workarounds

• Deploy a Web Application Firewall (WAF) with SQL injection protection rules as a temporary mitigation layer
• Restrict access to WordPress admin and AJAX endpoints using IP whitelisting where feasible
• Implement additional database user privilege restrictions to limit potential damage from successful exploitation
• Disable the Happy Addons for Elementor plugin entirely until an official patch is applied

# Disable the vulnerable plugin via WP-CLI until patched
wp plugin deactivate happy-elementor-addons

# Verify current plugin version
wp plugin get happy-elementor-addons --field=version

# Update to patched version when available
wp plugin update happy-elementor-addons

# Check for unauthorized admin users in the database
wp user list --role=administrator --fields=ID,user_login,user_email,user_registered
