Detailsinfo

A vulnerability, which was classified as problematic, has been found in Cozmos Labs TranslatePress Plugin up to 3.3.5. Affected by this issue is the function html_entity_decode of the component Translation Memory Suggestion Panel. The manipulation of the argument original with an unknown input leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. Impacted is integrity. CVE summarizes:

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.

The advisory is available at wordfence.com. This vulnerability is handled as CVE-2026-89412 since 09/11/2026. The exploitation is known to be easy. The attack may be launched remotely.
