Vulnerability from github – Published: 2026-03-03 14:48 – Updated: 2026-03-03 14:48

Summary
Rancher's Azure AD permission changes are not reflected on active sessions
Details

A bug has been identified in which permission changes in Azure AD are not 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.

Impact

This issue only affects Rancher instances with Azure AD integration enabled, regardless of the automatically refreshing settings which are enabled by default. The users that obtained a token (or kubeconfig) to access Rancher through the following sessions are affected by this issue: 1) Users using the Rancher UI. 2) Users using kubectl based on a kubeconfig downloaded through the Rancher UI. 3) Tokens created via the Rancher UI Create API Key feature.

Note that the permission caching is persisted even when the Rancher Manager pod is restarted. The only way for a user to get the new permissions is to logout and login again.

Patches

Patched versions include releases 2.6.13, 2.7.4 and later versions.

Mitigation MIT-46
Architecture and Design

Strategy: Separation of Privilege

  • Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
Mitigation MIT-1
Architecture and Design Operation

Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.

Mitigation MIT-49
Architecture and Design

Strategy: Separation of Privilege

Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
