CVE-2026-107718 · Severity: medium · CVSS 6.1 · Published 2026-10-08

AdonisJS is a Node.js web framework that uses route parameters to build URLs for redirects and links. When an application passes untrusted user input as a route parameter, an attacker can inject a path starting with "/" that causes the browser to redirect to an attacker-controlled website. This can be exploited for phishing attacks or to redirect users away from OAuth login flows.

## Technical details

The vulnerability exists in the shared createURL() helper used by Router.makeUrl() and Response.redirect().toRoute(), which fails to URI-encode route parameter values before appending them to URL segments. An attacker supplying a route parameter value like "/evil.example.com" causes the framework to generate a scheme-relative URL ("//evil.example.com") that browsers treat as an external redirect. Exploitation requires the application to define a route with a dynamic first path segment and pass request-derived data to that segment when constructing a redirect URL.
