Grafana Labs reports:

    On the 20th of August at 1800 CEST we were contacted about a potential
    security issue with the "remember me" cookie Grafana sets upon login. The
    issue targeted users without a local Grafana password (LDAP & OAuth users)
    and enabled a potential attacker to generate a valid cookie knowing only a
    username.

    All installations which use the Grafana LDAP or OAuth authentication
    features must be upgraded as soon as possible. If you cannot upgrade, you
    should switch authentication mechanisms or put additional protections in
    front of Grafana such as a reverse proxy.
