## Beschreibung

Spacebar Server before commit 8d126f4 contains a cross-channel message deletion vulnerability in the single-delete and bulk-delete message handlers that fail to scope message queries to the requested channel. Authenticated users with MANAGE_MESSAGES permission in any controlled channel can delete arbitrary messages in other channels by routing delete requests through their own channel.
