What is CVE-2025-12904?

The H5PxAPIkatchu plugin for WordPress contains a vulnerability that allows unauthenticated attackers to exploit the 'insert_data' AJAX endpoint. This flaw arises from inadequate input sanitization and output escaping, enabling the injection of arbitrary web scripts into pages.
