    Summary:

    Details: In SmartBear Collaborator Server through 13.3.13302, use of the Google Web Toolkit (GWT) API introduces a post-authentication Java deserialization vulnerability.

A malicious object can be submitted to the server via an authenticated attacker to execute commands on the underlying system.
