An information disclosure flaw was found in the way OpenShift restricted access to cron scripts. A local, authenticated user could use this flaw to gain access to cron scripts of other users, which could potentially contain sensitive information.
If it is fixed upstream, then OSE 2.2 will most likely ship it at some point, depending on the complexity.
Also it's a related bug that cron jobs don't share context with their corresponding gears, so that would be nice to fix.
