      "value": "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."

En las versiones de @adonisjs/http-server anteriores a la 7.8.1 y de la 8.0.0-next.0 a la 8.1.3, y en las versiones de @adonisjs/core anteriores a la 7.4.0, el método response.redirect().back() lee el encabezado Referer de la solicitud HTTP entrante y redirige a esa URL sin validar el host. Un atacante que puede influir en el encabezado Referer puede hacer que la aplicación redirija a los usuarios a un sitio externo malicioso. Esto afecta a todas las aplicaciones de AdonisJS que utilizan response.redirect().back() o response.redirect(’back’). Este problema ha sido solucionado en las versiones 7.8.1 y 8.2.0 y 7.4.0 de @adonisjs/core."
