CVE-2026-47188: Quest Bot improper output escaping in unban and unwarn commands

CVE-2026-47188 · Severity: info · CVSS 2.3 · Published 2026-06-11

Quest Bot is an open-source Discord bot used for server moderation and utility tasks. A flaw in the bot's unban and unwarn commands allows moderators to bypass standard mention restrictions to send mass notifications (like @everyone) to the entire server. This can be used to harass users or disrupt server operations by sending unauthorized pings that appear to come from a trusted bot.

Technical details

Quest Bot prior to version 1.0.5 is vulnerable to improper encoding or escaping of output (CWE-116) within its moderation modules. Specifically, the 'unban' and 'unwarn' commands fail to utilize the 'allowedMentions' property when echoing user-provided 'reason' text back to public channels. An attacker with basic moderator privileges (e.g., 'Ban Members' or 'Moderate Members') can include @everyone or @here tags in the reason field. The bot then broadcasts these mentions in a confirmation message, effectively bypassing Discord's standard permission checks for mass mentions. This issue is resolved in version 1.0.5.
