CVE-2026-104623 — MEDIUM (6.3)

Vulnerability Description

A security vulnerability exists in the authorization handling for the local (management) cluster shell feature of SUSE Rancher Manager 2.15.0 up to 2.15.3, 2.14.0 up to 2.14.7, 2.13.0 up to 2.13.11, 2.12.0 up to 2.12.15, 2.11.0 up to 2.11.19 and possible older versions. The authorization check that was introduced to protect this feature was not applied to every API route that can reach it, so an alternative request form reached the shell handler without the access check being evaluated. This could allow any authenticated users to run a pod on the management cluster.
