How to fix?

Upgrade org.opencastproject:opencast-kernel to version 8.1, 7.6 or higher.

Overview

org.opencastproject:opencast-kernel is a free and open source solution for automated video capture and distribution at scale.

Affected versions of this package are vulnerable to Improper Authorization. Enables a remember-me cookie based on a hash created from the username, password, and an additional system key. This means that an attacker getting access to a remember-me token for one server can get access to all servers which allow log-in using the same credentials without ever needing the credentials.

Such an attack will usually not work on different installations – assuming that safe, unique passwords are used – but it is basically guaranteed to work to get access to all machines of one cluster if a token from one machine is compromised.
