CVE-2026-89412 Details
Description
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.
A stored cross-site scripting vulnerability has been identified in the TranslatePress - Translate Multilingual Sites with AI Translation plugin for WordPress. This issue affects all versions up to and including 3.3.5. The vulnerability arises from inadequate input sanitization and output escaping in the Translation Memory Suggestion Panel. Unauthenticated attackers can exploit this flaw to inject arbitrary web scripts into pages, which will be executed when a user accesses the compromised page. The exploitation is made possible because the plugin's front-end rendering process decodes entity-encoded payloads before saving them, and the original column in the translation dictionary is not subjected to proper filtering, allowing the injected scripts to be executed in the administrator's session.
Users are advised to update the TranslatePress - Translate Multilingual Sites with AI Translation plugin to the latest version.
