The Supervisor in Sandstorm doesn't set and enforce the resource limits of a process. This allows remote attackers to cause a denial of service by launching a fork bomb in the sandbox, or by using a large amount of disk space.

A remote attacker could bypass the Sandstorm organization restriction before build 0.203 via a comma in an email-address field.

Sandstorm before build 0.203 allows remote attackers to read any specified file under /etc or /run via the sandbox backup function. The root cause is that the findFilesToZip function doesn't filter Line Feed (\n) characters in a directory name.

A Server Side Request Forgery vulnerability exists in the install app process in Sandstorm before build 0.203. A remote attacker may exploit this issue by providing a URL. It could bypass access control such as firewalls that prevent the attackers from accessing the URLs directly.
