Medium (4.1) in keystonejs keystone. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in @keystone-6/auth 7.0.0.
Keystone is a content management system for Node.JS. There is an open redirect in the `@keystone-6/auth` package versions 7.0.0 and prior, where the redirect leading `/` filter can be bypassed. Users may be redirected to domains other than the relative host, thereby it might be used by attackers to re-direct users to an unexpected location. To mitigate this issue, one may apply a patch from pull request 8626 or avoid using the `@keystone-6/auth` package.
