In all versions of GitLab CE/EE, an attacker with physical access to a
user’s machine may brute force the user’s password via the change password
function. There is a rate limit in place, but the attack may still be
conducted by stealing the session id from the physical compromise of the
account and splitting the attack over several IP addresses and passing in
the compromised session value from these various locations.
