Vulnerability Description
The Translate Multilingual sites – TranslatePress plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in versions up to, and including, 3.2.5. This is due to the translate_page() function unconditionally replacing the plugin's internal #!trpst# and #!trpen# marker tokens with literal angle brackets across the entire HTML page output after WordPress has already sanitized and escaped user input — allowing the attacker to bypass WordPress's normal HTML escaping by using these tokens, which are not HTML special characters, in the search query. 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 specially crafted link.
