Hikka, a Telegram userbot, has vulnerability affects all users on all versions of Hikka. Two scenarios are possible. 1. Web interface does not have an authenticated session: attacker can use his own Telegram account to gain RCE to the server by authorizing in the dangling web interface. 2.

No known patches are available, but some workarounds are available. Use `--no-web` flag and do not start userbot without it; after authorizing in the web interface, close the port on the server and/or start the userbot with `--no-web` flag; and do not click "Allow" in your helper bot unless it is your explicit action that needs to be allowed.
