Summary

In specific versions of Jenkins, the Stapler web framework improperly handles file uploads by creating temporary files in the system's default temporary directory. Due to the default permissions assigned to these files, unauthorized users with access to the Jenkins controller file system could potentially exploit this vulnerability. They may read or write to these temporary files before they are processed by the system, leading to possible data leaks or manipulation.
