Researchers disclosed a zero-click vulnerability in Telegram's emoji feature at a security conference in Tokyo, demonstrating that attackers can execute code on iOS devices without any user interaction. However, Telegram disputed the risk assessment of the vulnerability, and the current information does not specify the specific scope of its impact or the progress of any fixes. Note: A zero-click vulnerability is a high-risk vulnerability where attackers can trigger intrusion without the user clicking, opening, or performing any action; common entry points include voice calls, message previews, webpage rendering, audio decoding, and wireless debugging.
