** UNSUPPORTED WHEN ASSIGNED ** Deserialization of Untrusted Data vulnerability in Apache Shindig.
This issue affects Apache Shindig: all versions.
Users with access to the Shindig REST API can send specially-crafted requests to trigger arbitrary code execution on the server.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
