Description
AI Translation Available
The 'secret chat' feature in Telegram 4.9.1 for Android has a 'side channel' in which Telegram servers send GET requests for URLs typed while composing a chat message, before that chat message is sent. There are also GET requests to other URLs on the same web server. This also affects one or more other Telegram products, such as Telegram Web-version 0.7.0. In addition, it can be interpreted as an SSRF issue. NOTE: a third party has reported that potentially unwanted behavior is caused by misconfiguration of the 'Secret chats > Preview links' setting
