What the vulnerability does

01Description

The TranslatePress – Translate Multilingual sites with AI Translation plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Approved Comment Body Rendered in Translation Editor Strings Dropdown in all versions up to, and including, 3.2.6 due to insufficient input sanitization and output escaping.
