CVE-2020-36826Network attack vector

Script execution via incomplete HTML filtering

Published Mar 25, 2024 · Updated Apr 10, 2025

Cross-site scripting in AwesomestCode LiveBot allows remote authenticated users to alter rendered content through a crafted Discord message. The parseMessage routine used an incomplete regular expression to replace HTML tags, leaving crafted angle-bracket input available to the renderer. A malicious Discord user must send content that a LiveBot user views; successful exploitation changes client-rendered content and requires user interaction.
