  "details": "### Impact\n\nThe `response.redirect().back()` method in `@adonisjs/http-server` is vulnerable to open redirects. The method reads the `Referer` header from the incoming HTTP request and redirects to that URL without validating the host. An attacker who can influence the `Referer` header (for example, by linking a user through an attacker-controlled page before a form submission) can cause the application to redirect users to a malicious external site.\n\nThis affects all AdonisJS applications that use `response.redirect().back()` or `response.redirect(\u0027back\u0027)`.\n\nThe vulnerability is classified as CWE-601: URL Redirection to Untrusted Site (\u0027Open Redirect\u0027).\n\n### Patches\n\nThis has been fixed in `@adonisjs/http-server` version **8.2.0**. The `back()` method now validates the `Referer` header\u0027s host against the request\u0027s own `Host` header. Referrers from unrecognized hosts are rejected and the redirect falls back to `/` (or a developer-provided fallback URL).\n\nApplications that operate across multiple domains can configure additional trusted hosts via the `redirect.allowedHosts` option in `config/app.ts`.\n\nUsers should upgrade to `@adonisjs/http-server@^8.2.0` (or `@adonisjs/core@^7.4.0` if using the core meta-package).\n\n### Workarounds\n\nIf upgrading is not immediately possible, avoid using `response.redirect().back()` in routes that are reachable by unauthenticated users or from pages that accept external traffic. Instead, redirect to a known safe path explicitly using `response.redirect().toPath(\u0027/dashboard\u0027)`.\n\n### References\n\n- [CWE-601: URL Redirection to Untrusted Site](https://cwe.mitre.org/data/definitions/601.html)\n- [OWASP: Unvalidated Redirects and Forwards](https://cheatsheetseries.owasp.org/cheatsheets/Unvalidated_Redirects_and_Forwards_Cheat_Sheet.html)",
