## Description

The WPLP Cookie Consent plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the script blocker's output buffer processing in all versions up to, and including, 4.4.6. This is due to the plugin turning the fixed placeholder token '_LT_' back into '<' (and '_NL_'/'_RNL_' into line breaks) everywhere in the front-end page output, so user-controlled text that the page prints already escaped, such as a search term, can become HTML markup. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that run if they can trick a user into clicking a crafted link. The script blocker must be enabled.
