{"id":"CVE-2026-107768","kind":"vulnerability","aliases":["CVE-2026-107768"],"related":[],"title":"TranslatePress WordPress plugin: unauthenticated stored XSS via comment parameter","description":"The TranslatePress – Translate Multilingual sites with AI Translation plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 3.3.7 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. Exploitation requires the target site to allow unmoderated comment submission on at least one post and to have a secondary language configured — both conditions reflect TranslatePress's primary use case.","summary":"The TranslatePress WordPress plugin up to and including 3.3.7 does not sanitize the 'comment' parameter or escape its output.
