Description

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for red-discordbot, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update red-discordbot to 3.5.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5jq8-q6rj-9gq4 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
