Technical details

Quest Bot (prior to version 1.1.6) fails to implement mention suppression when displaying stored warning reasons via the /warns command. While the bot correctly suppresses mentions during the initial /warn command, the 'reason' string is stored in the database without sanitization or encoding. When a user later invokes /warns, the bot outputs the raw string containing @everyone or @here tags. If the bot has the 'Mention @everyone, @here, and All Roles' permission in the Discord guild, this results in a mass notification. This is classified as improper encoding or escaping of output (CWE-116). The issue is patched in version 1.1.6.
