The advisory
Floci 1.1.0 before 2.2.0 contains a code injection vulnerability in VtlTemplateEngine that allows unauthenticated attackers to execute commands via unrestricted Velocity mapping templates. Attackers can create a REST API with a MOCK integration whose template uses $util reflection to reach Runtime or ProcessBuilder, executing OS commands in the Floci JVM.
Check your whole app
Dependencies are only half of it. Free and read-only: before you push, run npx shippable-dev scan localhost:3000 in your project folder, no account needed. For your live app, you prove it's yours with a one-line tag first.
