Details

Actstream (short for Activity Stream) aggregates a user's activity from external services (RSS feeds, etc.) into per-user activity stream entities.

The configuration route does not sufficiently check that the user editing it is the account owner (or a user administrator) leading to an access bypass vulnerability.
