CyberRota Analysis
AI-GeneratedThe vulnerability in ash_typescript allows attackers to exploit path parameters to redirect client requests, potentially exposing sensitive credentials to untrusted external sites. This occurs due to improper handling of URL parameters, which can be manipulated to create protocol-relative URLs that direct traffic to malicious domains. Organizations using ash_typescript versions from 0.15.0 to before 0.18.0 should prioritize remediation to mitigate the risk of credential leakage and unauthorized access.

Original NVD Description
URL Redirection to Untrusted Site ('Open Redirect') vulnerability in ash-project ash_typescript allows an attacker who controls a path-parameter value to redirect a generated client's request, and the credentials attached to it, to an unintended route or an external origin. The URL builders in lib/ash_typescript/typed_controller/codegen/route_renderer.ex replace each :param placeholder with a bare template interpolation and never call encodeURIComponent, so the value reaches executeTypedControllerRequest raw. A value containing ../ is normalised away by the fetch URL resolver and reaches a different route, while ? or # truncates the path and can smuggle or override query parameters. For a route whose path begins with a parameter, a value such as /evil.example.com/x yields the protocol-relative URL //evil.example.com/x, sending the request and the credentials from TypedControllerConfig to an attacker-controlled host. Nothing constrains the value at runtime: get_path_param_type/2 emits only a TypeScript type, which is erased. The query-string path is unaffected, since URLSearchParams.set encodes its own values. This issue affects ash_typescript: from 0.15.0 before 0.18.0.
