What it is

The TranslatePress – Translate Multilingual sites with AI Translation plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content (URL-encoded gettext markers) in all versions up to, and including, 3.2.6 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. Comment moderation may delay exploitation for first-time commenters, but does not prevent it, as the payload uses only WordPress-permitted tags and attributes with percent-encoded characters that pass wp_kses URL validation unmodified.
