What is CVE-2024-39905?

CVE-2024-39905 is a medium-severity missing authorization vulnerability in Cog-Creators Red-DiscordBot, published on 11 Jul 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

Red is a fully modular Discord bot. Due to a bug in Red's Core API, 3rd-party cogs using the `@commands.can_manage_channel()` command permission check without additional permission controls may authorize a user to run a command even when that user doesn't have permissions to manage a channel. None of the core commands or core cogs are affected. The maintainers of the project are not aware of any _public_ 3rd-party cog utilizing this API at the time of writing this advisory. The problem was patched and released in version 3.5.10.
