Cloudbees · Jenkins · CVE-2016-3721
**Name of the Vulnerable Software and Affected Versions**
Jenkins versions prior to 2.3
Jenkins LTS versions prior to 1.651.2
**Description**
The issue allows remote authenticated users to inject arbitrary build parameters into the build environment via environment variables. This can be achieved by manipulating environment variables.
**Recommendations**
For Jenkins versions prior to 2.3, update to version 2.3 or later to resolve the issue.
For Jenkins LTS versions prior to 1.651.2, update to version 1.651.2 or later to resolve the issue.
As a temporary workaround, consider restricting access to environment variables in the build environment until a patch is available.
