CVE-2026-48485 duck-organization CVE debrief
CVE-2026-48485 is a low-severity vulnerability in Quest Bot, an open-source Discord Bot. Prior to version 1.1.6, the bot suppresses mentions when creating, unbanning, unwarning, kicking, muting, and unmuting, but stored warning reasons are still printed by /warns without mention suppression. This allows a moderator to 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. The vulnerability has been patched in version 1.1.6.
