Quest Bot is an opensource Discord Bot. Prior to 1.1.9, the image to GIF command uses a request helper that validates a hostname's public IP addresses but then sends the actual request by hostname, causing a second DNS lookup. An attacker controlling a domain can return a public address during validation and an internal address during the connection, bypassing the internal-address protection through DNS rebinding. The command takes its address directly from user input and its developer-only gate is disabled in normal deployments, so any member of a server with the bot can trigger the flaw without special permissions. Requests are restricted to HTTPS on port 443, and content is returned only when the response is a genuine image. The impact is therefore mostly blind internal probing with limited retrieval of image responses from loopback or internal endpoints, not arbitrary internal-data disclosure. Common cloud metadata services using plain HTTP on another port are not reachable through this path. This issue is fixed in version 1.1.9.
