Advisory GHSA-mq23-vvg7-xfm4 references a vulnerability in the following Go modules:

Module
github.com/rancher/rancher

Description:

Impact

A vulnerability in Rancher has been discovered, leading to a local user impersonation through SAML Authentication on first login.

The issue occurs when a SAML authentication provider (AP) is configured (e.g. Keycloak). A newly created AP user can impersonate any user on Rancher by manipulating cookie values during their initial login to Rancher. This vulnerability could also be exploited if a Rancher user (present on the AP) is removed, either manually or automatically via the [User Retention feature](https://ranchermanager.docs.rancher.com/how-to-guides/advanced-user-guides/enable...
