A Improper Privilege Management vulnerability in SUSE Rancher, allows users with access to the escalate verb on PRTBs to escalate permissions for any -promoted resource in any cluster. This issue affects: SUSE Rancher Rancher versions prior to 2.5.17; Rancher versions prior to 2.6.10.

GHSA-7m72-mh5r-6j3r — Privilege escalation in project role template binding (PRTB) and -promoted roles

Affected: Go: github.com/rancher/rancher

### Impact

An issue was discovered in Rancher versions from 2.5.0 up to and including 2.5.16 and from 2.6.0 up to and including 2.6.9, where an authorization logic flaw allows privilege escalation via project role template binding (PRTB) and `-promoted` roles. This issue is not present in Rancher 2.7 releases.

Note: Consult Rancher [documentation](https://ranchermanager.docs.rancher.com/how-to-guides/new-user-guides/authentication-permissions-and-global-configuration/manage-role-based-access-control-rbac/cluster-and-project-roles) for more information about cluster and project roles and [KB 000020097](https://www.suse.com/support/kb/doc/?id=000020097) for information about `-promoted` roles.

This privilege escalation is possible for users with access to the `escalate` verb on PRTBs (`projectroletemplatebindings.management.cattle.io`), including users with `*` verbs on PRTBs (see notes below for more information). These users can escalate permissions for any `-promoted` resource (see the table below for a full enumeration) in any cluster where they have a PRTB granting such permissions in at least one project in the cluster.

On a default Rancher setup, only the following roles have such permissions:

1. Project Owner 2. Manage Project Members

These roles have permissions to affect the following resources:

| Resource | API Group | Affected Rancher version | | - | - | - | | navlinks | ui.cattle.io | 2.6 | | nodes | "" | 2.6 | | persistentvolumes | "" | 2.5, 2.6 | | persis…
