FastAPI route handler invokes validate_code() (which internally compiles and execs attacker-supplied Python source) without an authentication dependency declared in the route decorator. Because Python evaluates function-definition decorators and default-argument expressions at the moment exec() processes the definition, an unauthenticated attacker can embed
