Doc Text:
A flaw was found in AdonisJS HTTP Server. The route URL generation helper fails to properly encode parameter values when constructing redirect destinations. A remote attacker can exploit this flaw by supplying a crafted path parameter starting with a forward slash, generating a scheme-relative external web address. This issue allows attackers to redirect users from a trusted application to a malicious external website, facilitating phishing attacks and the abuse of authentication workflows.

Description OSIDB Bzimport 2026-10-14 01:41:30 UTC 
AdonisJS HTTP Server is a package for handling HTTP requests in the AdonisJS framework. Prior to 8.2.3 and 9.3.0, AdonisJS HTTP Server inserts route parameter values into URLs without encodeURIComponent in the shared createURL() helper used by Router.makeUrl() and Response.redirect().toRoute(). If an application places attacker-controlled data in a dynamic first path segment and uses the generated route URL as a redirect destination, a value beginning with a slash can produce a scheme-relative external URL. Wildcard parameters are affected by the same missing encoding, while APIs intentionally accepting complete redirect URLs are not affected. An attacker can redirect users from a trusted application to an attacker-controlled site, facilitating phishing or abuse of authentication and OAuth flows. This issue is fixed in versions 8.2.3 and 9.3.0.
