Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

In SmartBear Collaborator Server through 13.3.13302, use of the Google Web Toolkit (GWT) API introduces a post-authentication Java deserialization vulnerability. The application's UpdateMemento class accepts a serialized Java object directly from the user without properly sanitizing it. A malicious object can be submitted to the server via an authenticated attacker to execute commands on the underlying system.
