Update URLs – Quick and Easy way to search old links and replace them with new links in WordPress <= 1.4.1 - Unauthenticated Open Redirect

Description

The Search & Replace Everything – Quick and Easy Way to Find and Replace Text, Links plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 1.4.1. This is due to insufficient validation on a redirect url supplied. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.
