Description

Quest Bot is an opensource Discord Bot. Prior to version 1.1.6, the purge and slowmode commands check only guild-level permissions on the invoking member. They do not check the member’s effective permissions in the channel where the command is run. A user denied channel-level moderation permissions can still delete messages or change slowmode through the bot. This issue has been patched in version 1.1.6.
