WC1C WordPress Plugin Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in the WC1C plugin for WordPress, affecting all versions through 0.23.0. The issue arises from the 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.
