CWE-378  (opens in a new tab)

How to fix?

Upgrade org.jenkins-ci.main:jenkins-core to version 2.375.4, 2.387.1, 2.394 or higher.

Overview

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

Affected versions of this package are vulnerable to Creation of Temporary File With Insecure Permissions when an administrator uploads a file with default permissions, which may be overly permissive. This could allow users to inject files into the Jenkins controller during the installation of a plugin.

Workaround

This vulnerability can be avoided by setting a different path as the default temporary directory, using the java.io.tmpdir system property.
