Summary

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.

Affected Version(s)

WP 404 Auto Redirect to Similar Post * <= 1.0.3

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
