CVE-2026-48485: CWE-116: Improper Encoding or Escaping of Output in duck-organization questbot
Quest Bot is an opensource Discord Bot. Prior to version 1.1.6, the latest release suppresses mentions when creating, unbanning, unwarning, kicking, muting, and unmuting, but stored warning reasons are still printed by /warns without mention suppression. A moderator can create a warning with @everyone or @here in the reason, then make the bot later output that reason through /warns, causing a mass ping if the bot has permission. This issue has been patched in version 1.1.6.
AI Analysis
Technical Summary
CVE-2026-48485 describes an improper encoding or escaping of output (CWE-116) in the Quest Bot Discord bot. Before version 1.1.6, while the bot suppressed mentions in certain commands, it did not suppress mentions stored in warning reasons when outputting them with the /warns command. This allowed a moderator with permission to create a warning containing mass-mention tags (@everyone, @here) that the bot would later output, triggering mass pings. The vulnerability was patched in version 1.1.6.
Potential Impact
The vulnerability can cause unwanted mass mentions in Discord channels when the bot outputs stored warning reasons containing mention tags. This can lead to user annoyance and potential disruption in Discord communities. The CVSS score is low (2.1), indicating limited impact and requiring high privileges (moderator) to exploit.
Mitigation Recommendations
Upgrade Quest Bot to version 1.1.6 or later, where mention suppression in warning reasons output has been implemented. No other mitigation is necessary as the issue is fixed in this version.
