Published Feb 5, 2024 · Updated Apr 8, 2026 · Assigned by Wordfence

Vendor: hwk-fr Product: WP 404 Auto Redirect to Similar Post Category: Web / CMS

Description

The WP 404 Auto Redirect to Similar Post plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘request’ parameter in all versions up to, and including, 1.0.3 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.
