CVE-2026-47163: CWE-862: Missing Authorization in duck-organization quest-bot
Quest Bot is an opensource modern Discord Bot built for moderation, utilities and support. Prior to version 1.0.1, any guild member who can invoke slash commands can use /automod add, /automod remove, and /automod list because the command has no Discord default permission requirement and no runtime moderator permission check. An attacker can add a rule matching common text and make the bot delete other users’ messages. This issue has been patched in version 1.0.1.

Technical Summary
CVE-2026-47163 is a missing authorization vulnerability (CWE-862) in the duck-organization quest-bot prior to version 1.0.1. The bot's slash commands for automod management lacked Discord default permission requirements and runtime moderator permission checks. As a result, any guild member with slash command access could add or remove automod rules, potentially deleting messages from other users. The vulnerability has been patched in version 1.0.1.
Potential Impact
An attacker with the ability to invoke slash commands in a Discord guild could add or remove automod rules without proper authorization. This could lead to unauthorized deletion of messages from other users, impacting message integrity and moderation controls within the Discord server.
Mitigation Recommendations
Upgrade quest-bot to version 1.0.1 or later, where the missing authorization checks have been implemented to restrict automod commands to authorized moderators only. No other mitigation is indicated.
