Telegram restricts regular bots from sending HTML elements

TechFlow reports: On November 15, according to The Defiant, Aliaksei Levin, a contributor to the Telegram Bot API, confirmed that regular bots currently cannot send HTML components, and private chats are also restricted. This restriction targets component delivery and does not imply a full shutdown of Mini Apps on Telegram.A developer previously stated that their bot was able to send components during part of the period from November 10 to 13, before subsequently encountering permission errors. The report noted that it remains unclear what triggered the restriction and when service will be restored.This restriction occurred after researchers disclosed security vulnerabilities in older client versions. Telegram founder Pavel Durov stated that the relevant issues have been resolved on the server side; researchers noted that the disclosed vulnerabilities have been patched in the current client version.
