Grafana 2.x, 3.x, and 4.x before 4.6.4 and 5.x before 5.2.3 allows authentication bypass because an attacker can generate a valid remember me cookie knowing only a username of an LDAP or OAuth user.

Weakness

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
