CVE-2026-47173: CWE-116: Improper Encoding or Escaping of Output in duck-organization quest-bot
Quest Bot, an open-source Discord moderation bot, had a vulnerability prior to version 1.0.3 where user-supplied ticket reasons containing mentions like @everyone, @here, user, or role mentions were posted without suppressing these mentions. This allowed an attacker to cause the bot to ping staff or all users with access to the ticket channel. The issue is fixed in version 1.0.3.
AI Analysis
Technical Summary
CVE-2026-47173 describes an improper encoding or escaping of output (CWE-116) vulnerability in the duck-organization's Quest Bot. Before version 1.0.3, the bot did not suppress mentions in user-provided ticket reasons, allowing an attacker to trigger unwanted pings to staff or everyone in the ticket channel if the bot had permission to mention them. This behavior was corrected in version 1.0.3 by properly handling mentions to prevent abuse.
Potential Impact
An attacker with the ability to create tickets can cause the bot to send messages that ping all users or specific roles, potentially leading to spam, annoyance, or disruption of staff workflows. There is no indication of privilege escalation or data compromise beyond the mention abuse.
Mitigation Recommendations
Upgrade Quest Bot to version 1.0.3 or later, where the issue is patched. No additional mitigation is required as the fix properly suppresses mentions in ticket reasons.
