Other reported vulnerabilities
[Fixed] There was a vulnerability in the framework that allows remote injection of resources, such as super credits, medals, samples, requisition credits, etc.
[Fixed] The Game Master system had poor RBAC controls - allowing a malicious user to perform some Joel-like actions.
[Fixed] Using the same remote injection vulnerability, a malicious user could do the opposite of inject resources - they could remove resources.
