ash_typescript 中 ash-project 的“输入验证不当”漏洞，允许远程攻击者向带类型控制器的路由提交超出已声明白名单或取值范围的参数值。 AshTypescript.TypedController.RequestHandler（位于 lib/ash_typescript/typed_controller/request_handler.ex）调用了 Ash.Type.cast_input/3，并将返回的 {:ok, cast} 结果视为“已完全验证”。在 Ash 中，这实际上是两个独立的步骤：c

Vulnerability Title
Declared argument constraints not enforced on AshTypescript typed controller routes
来源: CVE Program / CVE List V5
Vulnerability Description
Improper Input Validation vulnerability in ash-project ash_typescript allows a remote attacker to submit argument values outside a declared allowlist or bound on typed-controller routes.
AshTypescript.TypedController.RequestHandler in lib/ash_typescript/typed_controller/request_handler.ex calls Ash.Type.cast_input/3 and treats an {:ok, cast} result as fully validated. In Ash these are separate steps: cast_input/3 only coerces the term, while every constraint declared on the argument is applied by Ash.Type.apply_constraints/3, which this path never calls. Constraints such as one_of, max_length, min and max, and match are therefore inert, so a value outside a declared allowlist is accepted and passed to the route handler. Codegen renders the same constraints into the generated TypeScript types, so an allowlist appears enforced to a TypeScript caller while any other HTTP client ignores it. Empty-string to nil normalization also lives in apply_constraints, so the allow_nil?: false check accepts "" for a required argument.
Where a constraint gates a role, a status, or a sort direction, this becomes a privilege or state-machine bypass.
This issue affects ash_typescript: from 0.15.0 before 0.18.0.
