ReCaptcha Integration for WordPress Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in the ReCaptcha Integration for WordPress plugin, affecting all versions through 1.2.5. The issue arises from the plugin's use of add_query_arg without proper escaping, allowing unauthenticated attackers to inject arbitrary web scripts. These scripts could be executed if a user is tricked into clicking a link.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where an attacker can inject scripts that are executed in the context of the user's browser.

Remediation

Users can update to version 1.2.6 or a newer patched version to address this vulnerability.
