Upgrading to version 109.4 is able to resolve this issue. Patch name: 8a3946bd0a54bfb72a4d57179fcd253f2c550cd7. The affected component should be upgraded. The vendor was informed early about this issue. They classify it as a \"Self-XSS\". They deployed a countermeasure: \"Nevertheless, we consider this a violation of secure coding standards. The lack of filtering via `htmlspecialchars()` has already been fixed in the latest patch to prevent incorrect data display.\""
