Reflected Cross-Site Scripting in Unlimited Elements For Elementor Plugin

Publication date: 2026-09-05

Last updated on: 2026-09-05

Assigner: Wordfence

Description
The Unlimited Elements For Elementor plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via 'formData[id]' Parameter in all versions up to, and including, 2.0.17 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The front-end AJAX handler is registered on the public 'wp' action with no nonce, capability, or referer check, and the raw attacker-controlled id value is interpolated verbatim into an exception message that is echoed back without escaping; when the response is served as text/html rather than application/json, the browser parses the injected markup.

Executive Summary

The Unlimited Elements For Elementor WordPress plugin has a reflected cross-site scripting (XSS) vulnerability due to insufficient input sanitization and output escaping in the 'formData[id]' parameter. This allows unauthenticated attackers to inject malicious scripts into web pages. The vulnerability exists because the plugin's front-end AJAX handler lacks nonce, capability, or referer checks, and the attacker-controlled 'id' value is directly inserted into an error message without proper escaping.

When the response is served as text/html instead of application/json, the browser may execute the injected script if a user clicks a malicious link.

Impact Analysis
  • Unauthenticated attackers could steal sensitive user data like cookies or session tokens.
  • Malicious scripts could redirect users to phishing sites or perform actions on their behalf.
  • Attackers might deface websites or spread malware through injected scripts.
  • Users visiting compromised pages could have their accounts compromised without realizing it.
Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR's data protection principles and HIPAA's security requirements for safeguarding protected health information. Organizations may face fines or penalties for failing to protect user data adequately.

Mitigation Strategies

Update the Unlimited Elements For Elementor plugin to the latest version beyond 2.0.17 to address the XSS vulnerability. Remove or disable the plugin if updates are unavailable. Monitor network traffic for suspicious activity related to unauthenticated AJAX requests.
