Message deletion via unauthorized AutoMod rule changes

Published Jun 11, 2026 · Updated Jun 11, 2026

Missing authorization in Vantern Quest Bot before 1.0.1 allows remote authenticated users to alter server-wide AutoMod rules. The /automod add, remove, and list handlers define no default Discord permission and perform no runtime moderator check before storing, exposing, or deleting guild rules. Any guild member who can invoke slash commands can add a broad match that deletes other users' messages or remove existing moderation rules when the bot can delete messages.
