Apache Shindig Common, Apache Shindig Social-Api: Remote Code Execution via XStream deserialization (OpenSocial REST API)

** 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. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

The gadget renderer in Apache Shindig 2.5.0 for PHP allows remote attackers to obtain sensitive information via an XML document containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.
