Buildbot before 1.8.2 and 2.x before 2.3.1 accepts a user-submitted authorization token from OAuth and uses it to authenticate a user. If an attacker has a token allowing them to read the user details of a victim, they can login as the victim.
Weakness
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
