The library commons-io contains a vulnerability in all released versions. The correction is planned for 2.7, but unreleased yet. To prevent any issue with this library, please ensure you are not using FileNameUtils.normalize and post your analysis here.

Ticket to follow the vulnerability:

https://issues.apache.org/jira/browse/IO-559

Although the plugin may not use the dependency the way it's exploitable, it's better to avoid the buggy dependency in order to:

• avoid security reports warning about that
• avoid future risky uses of the library that may exploit the vulnerability
  If you like, you can use the bom approach to avoid dealing with the right version, it will take the one used by Jenkins core: https://jenkins.io/doc/developer/plugin-development/dependency-management/

Thank you.
