TranslatePress <= 3.3.5 - Unauthenticated Stored Cross-Site Scripting via Translation Memory Suggestion Panel
The TranslatePress – Translate Multilingual sites with AI Translation plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Translation Memory Suggestion Panel (v-html on suggestion.original) in all versions up to, and including, 3.3.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Unauthenticated attackers can seed the translation dictionary's original column with executable HTML because the front-end rendering pipeline decodes entity-encoded payloads via html_entity_decode() before persistence, and the original column is deliberately exempt from kses filtering — meaning no save-time sanitizer neutralizes the stored payload before it is later rendered in an administrator's session.
