    Published: 7 Oct 2026Last Modified: 7 Oct 2026

    Summary:

    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.
