An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in SUSE Rancher allows users in some higher-privileged groups to to inject code that is
executed within another user's browser, allowing the attacker to steal
sensitive information, manipulate web content, or perform other
malicious activities on behalf of the victims. This could result in a
user with write access to the affected areas being able to act on behalf
of an administrator, once an administrator opens the affected web page.
This issue affects Rancher: from >= 2.6.0 before < 2.6.13, from >= 2.7.0 before < 2.7.4.

An Improper Privilege Management vulnerability in SUSE Rancher allowed standard users to leverage their existing permissions to manipulate Kubernetes secrets in the local
cluster, resulting in the secret being deleted, but their read-level
permissions to the secret being preserved. When this operation was
followed-up by other specially crafted commands, it could result in the
user gaining access to tokens belonging to service accounts in the local cluster.
This issue affects Rancher: from >= 2.6.0 before < 2.6.13, from >= 2.7.0 before < 2.7.4.

A Improper Privilege Management vulnerability in SUSE Rancher causes permission changes in Azure AD not to be reflected to users
while they are logged in the Rancher UI. This would cause the users to
retain their previous permissions in Rancher, even if they change groups
on Azure AD, for example, to a lower privileged group, or are removed
from a group, thus retaining their access to Rancher instead of losing
it.
This issue affects Rancher: from >= 2.6.7 before < 2.6.13, from >= 2.7.0 before < 2.7.4.

Improper Privilege Management vulnerability in SUSE Rancher allows Privilege Escalation. A failure in the update logic of Rancher's admission Webhook may lead to
the misconfiguration of the Webhook. This component enforces validation
rules and security checks before resources are admitted into the
Kubernetes cluster.
The issue only affects users that upgrade from 2.6.x or 2.7.x to 2.7.2. Users that did a fresh install of 2.7.2 (and did not follow an upgrade path) are not affected.
