Description

In versions running on TYPO3 10 and 11, the configured OpenAI API key is embedded in every backend page, so that the editor plugin can contact the OpenAI service directly from the browser. Any authenticated backend user can read the key and use it at the expense of the site operator. This only applies if an API key has been configured.
