Besides the protocol issues, the app itself is not very secure. In February 2015, Zimperium published a detailed analysis of Telegram's local vulnerability, allowing the attacker to get full access to plain text messages.

Basically, even if the protocol was secure, the application itself isn't, becoming the weak link in secure communication.

According to Zimperium, the Telegram team has never responded to their vulnerability notification. It tells me something about their attitude to security in general, and goes in line, for example, with how they implement encrypted chats.

According to Zimperium, the Telegram team has never responded to their vulnerability notification. It tells me something about their attitude to security in general, and goes in line, for example, with how they implement "secure chats": no desktop support, graphical-only fingerprint of the key, no possibility to simply enter the key.
