CVE-2026-47189: CWE-639: Authorization Bypass Through User-Controlled Key in duck-organization quest-bot
Quest Bot is an opensource modern Discord Bot built for moderation, utilities and support. Prior to version 1.0.5, the AutoMod remove flow looks up and deletes rules by global database ID without verifying that the rule belongs to the guild where the command is executed. A user can learn a victim guild’s AutoMod rule ID through autocomplete, then remove that rule from another guild where they have Manage Server. This issue has been patched in version 1.0.5.
AI Analysis
Technical Summary
CVE-2026-47189 describes an authorization bypass in the Quest Bot's AutoMod remove functionality. Before version 1.0.5, the bot used global database IDs to identify AutoMod rules but failed to verify that the rule belonged to the guild where the removal command was executed. Consequently, a user with Manage Server permissions in one guild could remove AutoMod rules from a different guild by learning the victim guild's rule ID via autocomplete. This issue is classified under CWE-639 (Authorization Bypass Through User-Controlled Key). The vulnerability has been fixed in Quest Bot version 1.0.5.
Potential Impact
An attacker with Manage Server permissions in one guild could remove AutoMod rules from other guilds where they do not have such permissions, potentially disrupting moderation policies across multiple Discord servers. This could lead to unauthorized modification or removal of moderation rules, impacting server security and management.
Mitigation Recommendations
This vulnerability has been patched in Quest Bot version 1.0.5. Users and administrators should upgrade to version 1.0.5 or later to remediate this issue. No other mitigation steps are indicated by the vendor advisory.
