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. Web interface does have an authenticated session: due to insufficient warning in the authentication message, users were tempted to click "Allow" in the "Allow web application ops" menu. This gave an attacker access not only to remote code execution, but also to Telegram accounts of owners. Scenario number 2 is known to have been exploited in the wild. 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.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
