CVE-2019-16248 Information

Description

The \delete for\ feature in Telegram before 5.11 on Android does not delete shared media files from the Telegram Images directory. In other words there is a potentially misleading UI indication that a sender can remove a recipient’s copy of a previously sent image (analogous to supported functionality in which a sender can remove a recipient’s copy of a previously sent message).
