AdonisJS HTTP Server is a package for handling HTTP requests in the AdonisJS framework. In versions 8.0.0-next.0 through 8.2.0 and 9.0.0 through 9.0.2, the error.message is interpolated into the default HTML exception response without escaping, allowing a crafted missing-route URL to execute attacker-controlled JavaScript when a victim opens it and no custom status page or JSON response handles the error. When debug mode is disabled and no custom status page handles the error, the default HTML renderer interpolates error.message directly into an HTML response. This issue is fixed in versions 8.2.1 and 9.1.0.
