CVE-2025-69319: Beaver Builder Code Injection Vulnerability

CVE-2025-69319 Overview

CVE-2025-69319 is a Code Injection vulnerability affecting the Beaver Builder WordPress plugin (beaver-builder-lite-version). This vulnerability allows attackers to inject and execute arbitrary code within WordPress installations utilizing the affected plugin versions. The vulnerability stems from improper control of code generation (CWE-94), enabling malicious actors to potentially compromise WordPress websites through arbitrary code execution.

Critical Impact

Successful exploitation could allow attackers to execute arbitrary code on affected WordPress installations, potentially leading to complete site compromise, data theft, or further network intrusion.

Affected Products

• Beaver Builder (beaver-builder-lite-version) through version 2.9.4.1
• WordPress installations utilizing vulnerable Beaver Builder plugin versions

Technical Details for CVE-2025-69319

Vulnerability Analysis

This vulnerability is classified as Improper Control of Generation of Code (CWE-94), commonly referred to as Code Injection. The Beaver Builder plugin, a popular WordPress page builder with significant market adoption, fails to properly sanitize or validate user-supplied input before incorporating it into dynamically generated code constructs.

Code injection vulnerabilities in WordPress plugins are particularly dangerous because they can provide attackers with the ability to execute arbitrary PHP code within the context of the WordPress application. Given WordPress's architecture, successful exploitation could grant attackers full control over the web server's WordPress instance.

Root Cause

The root cause of this vulnerability lies in the improper handling of user-controlled input within the Beaver Builder plugin's code generation mechanisms. When the plugin processes certain input parameters, it fails to adequately sanitize or escape values before they are incorporated into executable code paths. This lack of proper input validation allows attackers to inject malicious code that gets executed by the server.

Attack Vector

The attack vector for this vulnerability involves submitting specially crafted input to the Beaver Builder plugin that contains malicious code. When the vulnerable code processes this input without proper sanitization, the injected code is executed within the WordPress environment.

Attackers could potentially exploit this vulnerability by:

1. Crafting malicious payloads designed to bypass any existing input filters
2. Submitting these payloads through plugin interfaces that process user input
3. Triggering the code generation functionality to execute the injected code
4. Gaining arbitrary code execution capabilities on the target WordPress installation

Detection Methods for CVE-2025-69319

Indicators of Compromise

• Unexpected PHP files appearing in WordPress directories, particularly within plugin folders
• Unusual outbound network connections from the WordPress server
• Modified plugin files with injected code segments
• Suspicious entries in web server access logs indicating exploitation attempts
• Unexpected administrative user accounts created in WordPress

Detection Strategies

• Monitor WordPress plugin directories for unauthorized file modifications or new file creations
• Implement file integrity monitoring on Beaver Builder plugin files
• Review web application firewall (WAF) logs for code injection patterns targeting the Beaver Builder plugin
• Analyze PHP error logs for unexpected code execution errors or warnings

Monitoring Recommendations

• Deploy endpoint detection and response (EDR) solutions to monitor for suspicious process execution on WordPress servers
• Enable detailed logging for all WordPress administrative actions
• Implement real-time alerting for modifications to plugin files
• Configure web application firewalls to detect and block code injection attempts

How to Mitigate CVE-2025-69319

Immediate Actions Required

• Audit your WordPress installations to identify any instances running Beaver Builder version 2.9.4.1 or earlier
• Review WordPress user accounts for any unauthorized administrative access
• Inspect Beaver Builder plugin files for any signs of tampering or injected code
• Consider temporarily disabling the Beaver Builder plugin until a patched version is available and deployed

Patch Information

Organizations using the affected Beaver Builder plugin should monitor the official Beaver Builder update channels for security patches addressing this vulnerability. Check the Patchstack advisory for the latest patch information and update to a version newer than 2.9.4.1 when available.

Workarounds

• Implement web application firewall (WAF) rules to filter potential code injection payloads targeting Beaver Builder
• Restrict administrative access to WordPress to trusted IP addresses only
• Enable WordPress security hardening measures including disabling file editing through the admin panel
• Consider using security plugins that provide additional input validation and code execution monitoring

# WordPress configuration hardening
# Add to wp-config.php to disable file editing
define('DISALLOW_FILE_EDIT', true);

# Restrict plugin installation/updates (use with caution)
define('DISALLOW_FILE_MODS', true);
