Description
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.
