Summary
Red-DiscordBot vulnerable to Incorrect Authorization in commands API
Details

Impact

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 @commands.mod_or_can_manage_channel(), @commands.admin_or_can_manage_channel(), and @commands.guildowner_or_can_manage_channel() command permission checks are unaffected.

Patches

The problem was patched in PR #6398 and later released in version 3.5.10.

Workarounds

Any cog using the @commands.can_manage_channel() command permission check should be unloaded until an upgrade to a patched version can be performed.
