CVE-2026-47196Public exploitNetwork attack vector

Guild-wide message deletion via empty automod rule

Published Jun 12, 2026 · Updated Jun 12, 2026

Improper input validation in Vantern Quest Bot before 1.1.6 allows remote authenticated users to delete every non-bot guild message. AutoModCommand.chatInputRun trims the /automod add word option and stores the result without rejecting an empty string; MessageCreateListener.run then passes that value to content.includes(), for which an empty string always matches. Exploitation requires Manage Guild permission, a running bot with database persistence, and permission for the bot to delete messages; the empty rule disrupts guild chat until removed.
