The plugin includes a library (commons-io) with a vulnerability. Please update it to 2.6. In addition to that, a second vulnerability is present in 2.6 on the method FileNameUtils.normalize. As the correction is planned for 2.7 but this version is not yet released, please ensure you are not using this method in your code and provide your finding in this ticket.
Ticket to follow the second vulnerability:
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/
