Summary

Jenkins 2.587 and earlier, and LTS 2.580.1 and earlier, are affected. The HTTP endpoint that creates the first user account does not check whether the setup wizard has been completed, which causes a race condition (CWE-362). An unauthenticated remote attacker can create an administrator account while the initial user account is being replaced.

Description from the CNA
