MEDIUM 5.3EPSS 1.42%

Does this matter?

Lower severity and a low EPSS score (1.42%). Track it; it rarely justifies an emergency change on its own.

Description

A reordering issue exists in Telegram before 7.8.1 for Android, Telegram before 7.8.3 for iOS, and Telegram Desktop before 2.8.8. An attacker can cause the server to receive messages in a different order than they were sent a client.
