CVE-2017-1000505: Jenkins Script Security

Medium severity, CVSS 6.5. EPSS: 1% chance of exploitation in the next 30 days.

In Jenkins Script Security Plugin version 1.36 and earlier, users with the ability to configure sandboxed Groovy scripts are able to use a type coercion feature in Groovy to create new `File` objects from strings. This allowed reading arbitrary files on the Jenkins master file system. Such a type coercion is now subject to sandbox protection and considered to be a call to the `new File(String)` constructor for the purpose of in-process script approval.
