Executive brief
Quest Bot is an open-source Discord bot used for server moderation and support tickets. A flaw in the bot's configuration allows users with administrative permissions to redirect private support ticket transcripts to public or unauthorized channels. This could lead to the exposure of sensitive private conversations, user reports, and moderation evidence to individuals who should not have access to that information.
Technical details
An information disclosure vulnerability exists in Quest Bot prior to version 1.0.4 due to improper access control in the ticket transcript system. Users with high privileges (sufficient to run /settings) can configure the 'ticketTranscriptChannelId' to point to any channel they can read, even if they lack access to the original private ticket channels. When a ticket is closed, the bot generates a full transcript—including message history, participant tags, and attachment URLs—and sends it to the configured destination. This allows an attacker to bypass intended channel isolation and exfiltrate private ticket data. The issue is patched in version 1.0.4.
