Telegram disputes the risk assessment of a reported flaw in its sticker feature on iOS, according to a BlockBeats flash.
Reported demonstration
BlockBeats said researchers at a security conference in Tokyo demonstrated code execution without any interaction by the targeted user. The outlet described the issue as a zero-click vulnerability.
The flash did not identify the researchers, name affected app versions or say whether a fix was available. It reported Telegram’s disagreement without providing the company’s detailed response.
