Description Andrej Nemec 2018-10-25 09:21:10 UTC 
By accessing a specific crafted URL on Jenkins instances using Jenkins' own user database, users without Overall/Read access could create ephemeral user records.

This behavior could be abused to create a large number of ephemeral user records in memory.

Jenkins security policy[0]:

"Any security advisory related updates to Jenkins core or the plugins we include in the OpenShift Jenkins master image will only occur in the v3.11 and v4.x branches of this repository.

We do support running the v3.11 version of the master image against older v3.x (as far back as v3.4) OpenShift clusters if you want to pick up Jenkins security advisory updates."
