A Quassel core (server daemon) supports being used by multiple users, who all have independent settings, backlog and so on. The backlog is stored in a database shared by all users on a Quassel core, tagged with a user ID. However, some SQL queries didn't check for the correct user ID being provided. This has the undesired effect that the Quassel core can be tricked into providing the backlog for an IRC channel or query that does not belong to the user session requesting it. Doing this requires a manipulated client sending appropriately crafted requests to the core. This client also needs to be properly authenticated, i.e. to have supplied valid user credentials for one of the users on the core.
