Technical details
The VtlTemplateEngine component processes Velocity mapping templates without proper input validation, allowing attackers to create MOCK integrations that leverage Velocity's $util reflection features to access Java Runtime or ProcessBuilder classes. An unauthenticated attacker can craft a malicious REST API definition with a Velocity template that breaks out of the template sandbox and executes OS commands in the Floci JVM context.
