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.
