CVE-2026-2385 in The Plus Addons for Elementor Plugin
Summary
by MITRE • 02/22/2026
The The Plus Addons for Elementor – Addons for Elementor, Page Templates, Widgets, Mega Menu, WooCommerce plugin for WordPress is vulnerable to Insufficient Verification of Data Authenticity in all versions up to, and including, 6.4.7. This is due to the plugin decrypting and trusting attacker-controlled email_data in an unauthenticated AJAX handler without cryptographic authenticity guarantees. This makes it possible for unauthenticated attackers to tamper with form email routing and redirection values to trigger unauthorized email relay and attacker-controlled redirection via the 'email_data' parameter.

The vulnerability identified as CVE-2026-2385 affects the Plus Addons for Elementor plugin, a widely used WordPress extension that provides various addons including page templates, widgets, mega menus, and WooCommerce integration. This plugin serves as a critical component in many WordPress websites, particularly those utilizing the Elementor page builder for content creation and design. The vulnerability stems from insufficient verification of data authenticity within the plugin's architecture, specifically within its AJAX handler functionality that processes email-related data submissions. The affected versions range from the initial release up to and including version 6.4.7, indicating a substantial attack surface that could potentially impact numerous WordPress installations worldwide.
The technical flaw manifests in the plugin's handling of the 'email_data' parameter within an unauthenticated AJAX endpoint. When processing form submissions, the plugin decrypts and processes attacker-controlled data without implementing proper cryptographic authenticity checks or validation mechanisms. This design decision creates a critical security gap where any unauthenticated user can manipulate the email routing and redirection parameters that are typically protected. The vulnerability falls under CWE-295 which specifically addresses "Improper Certificate Validation" and related issues of insufficient data authenticity verification. The lack of cryptographic guarantees means that attackers can inject malicious email addresses, redirection URLs, or routing instructions that will be processed as legitimate by the vulnerable system.
The operational impact of this vulnerability is significant and multifaceted, creating potential for various malicious activities including unauthorized email relay and malicious redirection. Attackers can exploit this weakness to route form submissions through their own email servers, potentially enabling spam campaigns or phishing attacks that appear to originate from legitimate websites. The redirection capability allows threat actors to direct users to malicious websites or inject malicious content, effectively transforming the vulnerable plugin into a vector for social engineering attacks. This vulnerability particularly affects websites that rely on form submissions for contact information, lead generation, or customer service interactions, as these systems become vulnerable to manipulation without requiring any authentication credentials or privileged access.
The attack surface extends beyond simple data manipulation to include potential abuse of the plugin's integration with WooCommerce functionality, which could enable more sophisticated attacks targeting e-commerce sites. According to ATT&CK framework, this vulnerability maps to T1190 - Exploit Public-Facing Application, where attackers leverage weaknesses in web applications to gain unauthorized access to systems or data. The unauthenticated nature of the attack means that no prior access or credentials are required, making the exploitation particularly dangerous as it can be executed by anyone with access to the vulnerable website. Organizations should consider implementing network-level protections and monitoring for unusual email routing patterns or redirection attempts, as these may indicate exploitation attempts. The vulnerability highlights the critical importance of implementing proper input validation and cryptographic verification in web applications, particularly in plugins that handle user submissions and external communications.
Mitigation strategies should include immediate plugin updates to versions that address the authentication verification gap, as well as implementing additional security measures such as rate limiting on AJAX endpoints, monitoring for suspicious email routing patterns, and network segmentation to limit potential lateral movement. Security professionals should also consider implementing web application firewalls and intrusion detection systems that can identify and block malicious attempts to exploit this vulnerability. Regular security audits of WordPress plugins and themes should be conducted to identify similar authentication and validation weaknesses that could expose systems to similar attacks, particularly focusing on components that handle sensitive data processing or external communications.
