CVE-2026-89412: 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 htmlentitydecode() 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.

Event History
Frequently Asked Questions
Who can exploit this issue, and what interaction is required?
An unauthenticated attacker can inject executable HTML into the translation dictionary. The stored script executes when a user, including an administrator, accesses a page containing the injected content; no attacker authentication or victim interaction beyond viewing the affected page is required.
Which installations are affected?
All versions up to and including 3.3.5 are affected. The issue is in the Translation Memory Suggestion Panel handling of the translation dictionary's original column.
Why does the injected content persist instead of being sanitized?
The front-end pipeline decodes entity-encoded payloads with html_entity_decode() before storage. The original dictionary column is exempt from kses filtering, so there is no save-time sanitization to neutralize the payload before it is rendered.
