Overview

org.jenkins-ci.main:jenkins-core is an open source automation server.

Affected versions of this package are vulnerable to Improper Validation. It does not properly check that a newly created view has an allowed name. When a form to create a view is submitted, the name is included twice in the submission. One instance is validated, but the other instance is used to create the value. This allows attackers with View/Create permission to create views with invalid or already-used names.
