## Affected

- duck-organization quest-bot: fixed in 1.0.5

## Description

Quest Bot is an opensource modern Discord Bot built for moderation, utilities and support. Prior to version 1.0.5, the latest release suppresses mentions in several moderation commands, but /unban and /unwarn still echo user-controlled reason text in public bot messages without allowedMentions. A moderator can use @everyone or @here in the reason and make the bot send a mass ping. This issue has been patched in version 1.0.5.
