CVE-2025-23391Network attack vector

Administrator account takeover via improper privilege comparison

Published Apr 11, 2025 · Updated Feb 26, 2026

Incorrect privilege assignment in SUSE Rancher 2.8.0 through 2.8.13 allows remote authenticated users to take over Administrator accounts. Rancher's user edit authorization allowed Restricted Administrators without manage-users to change passwords for users whose rules exceeded their own. Exploitation requires the Restricted Administrator role and can grant control of a more privileged account; deployments not using that role are unaffected.
