Remote Code Execution in Red Discord Bot

Impact

A RCE exploit has been discovered in the Trivia module: this exploit allows Discord users with specifically crafted usernames to inject code into the Trivia module’s leaderboard command. By abusing this exploit, it’s possible to perform destructive actions and/or access sensitive information.

Patches

This critical exploit has been fixed on version 3.3.11.

Workarounds

Unloading the Trivia module with unload trivia can render this exploit not accessible. We still highly recommend updating to 3.3.11 to completely patch this issue.
