CVE-2024-8874

MEDIUM

AJAX Login and Registration modal popup + inline form <= 2.24 - Reflected XSS via add_query_arg

Title source: llm

Description

The AJAX Login and Registration modal popup + inline form plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 2.24. 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.
