Description Sam Fowler 2018-08-23 04:42:51 UTC 
Jenkins before LTS version 2.121.3 and weekly version 2.138 allow unauthorized users to access agent logs.

Users with Overall/Read permission were able to access the URL serving agent logs on the UI due to a lack of permission checks.

Access to the affected URL is now limited to users with the correct Agent/Connect permission.

Comment 3 Jason Shepherd 2018-10-31 06:59:45 UTC 
By default Jenkins doesn't setup users without the Agent/Connect permission. It's possible to setup such users but it's best not to rely on Agent/Connect permission to prevent access to agent logs because of this issue on OpenShift Container Platform 3.10 and earlier.

Upgrade to OpenShift Container Platform 3.11 to pick up a fix for this issue.
