Summary

Apache Neethi does not impose any restrictions on URIs when manually fetching remote policy references through the PolicyReference API. When an application explicitly calls the API to retrieve a policy from a remote URI, an outbound request is made for arbitrary protocols and internal IP adddresses. From 3.2.2, only http or https URIs are allowed, and link-local/multicast/any-local addresses are forbidden.

Users are recommended to upgrade to version 3.2.2, which fixes this issue.
