    "title": "AdonisJS: Unencoded route parameters can produce open redirects",
    "summary": "Route parameters are inserted into generated URLs without URI encoding. When an application passes untrusted input to a route whose first path segment is dynamic, a value beginning with / can produce a scheme-relative URL. For example: ```ts router.get('/:page', handler).as('pages.show') response.redirect().toRoute('pages.show', { page: '/evil.example.com', }) ``` This generates the following redirect: ```http Location: //evil.example.com ``` Browsers interpret this value as an external URL and redirect the user to `https://evil.example.com`. ## Details The shared `createURL()` helper is used by route URL builders, including `Router.makeUrl()` and `Response.redirect().toRoute()`. Route parameter values were appended without encoding: ```ts if (isDefined) { uriSegments.push(`${value}${token.end}`) } ``` Wildcard parameters had the same behavior: ```ts uriSegments.push(`${values.join('/')}${token.end}`) ``` **The issue does not affect APIs that intentionally accept complete redirect URLs. Exploitation requires an application to pass attacker-controlled data as a route parameter and use the generated URL as a redirect destination.** ## Impact An attacker may craft a link on a trusted application domain that redirects a victim to an attacker-controlled website. This can facilitate phishing and may be chained with authentication or OAuth flows that rely on trusted redirect destinations. Applications are affected when they: - define a route whose first path segment is dynamic; and ",
