Technical details

Quest Bot prior to version 1.0.3 is vulnerable to improper output escaping (CWE-116) within its reminder functionality. The bot fails to sanitize user-provided strings or suppress mass mentions when replaying stored reminder messages. An attacker with basic user privileges can create a reminder containing '@everyone' or '@here' tags; when the scheduled task executes, the bot sends the message to the channel. If the bot has the 'Mention @everyone, @here, and All Roles' permission, Discord will process these as valid mass notifications. This issue is patched in version 1.0.3.
