Telegram

Telegram is a widely-used encrypted messaging and communication platform with millions of users globally. This high-severity vulnerability requires local access to the target system, some specific conditions to exploit (high complexity), and user interaction, but if successfully exploited grants an attacker high-level capabilities to compromise confidentiality, integrity, and availability of the system. Security teams should monitor for patches following the July 2026 vendor deadline and be alert for any exploitation attempts targeting local Telegram installations, particularly those targeting user endpoints.
