AdonisJS HTTP Server is a package for handling HTTP requests in the AdonisJS framework. In @adonisjs/http-server versions prior to 7.8.1 and 8.0.0-next.0 through 8.1.3, and @adonisjs/core versions prior to 7.4.0, the response.redirect().back() 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 can cause the application to redirect users to a malicious external site. This affects all AdonisJS applications that use response.redirect().back() or response.redirect('back'). This issue has been fixed in versions 7.8.1 and 8.2.0 and 7.4.0 of @adonisjs/core.

GHSA-6qvv-pj99-48qm — @adonisjs/http-server has an Open Redirect vulnerability

2026-10-08T19:42:57.793995+00:00

Affected: npm: @adonisjs/http-server, npm: @adonisjs/core

### Impact

The `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.

This affects all AdonisJS applications that use `response.redirect().back()` or `response.redirect('back')`.

The vulnerability is classified as CWE-601: URL Redirection to Untrusted Site ('Open Redirect').

### Patches

This has been fixed in `@adonisjs/http-server` version **8.2.0**. The `back()` method now validates the `Referer` header's host against the request's own `Host` header. Referrers from unrecognized hosts are rejected and the redirect falls back to `/` (or a developer-provided fallback URL).

Applications that operate across multiple domains can configure additional trusted hosts via the `redirect.allowedHosts` option in `config/app.ts`.

Users should upgrade to `@adonisjs/http-server@^8.2.0` (or `@adonisjs/core@^7.4.0` if using the core meta-package).

### Workarounds

If 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.…
