CVSS 6.1 · Medium EPSS 0,37%

Kerentanan Authorization Bypass Through User-Controlled Key pada suse rancher. Skor CVSS 3.1 6.1 (Medium) menurut NVD.

Deskripsi (NVD)

A flaw was found in Rancher Manager. The /v3/users update path did not enforce immutability of a User resource's `username` and `principalIds` fields. A user holding the `update` verb on `users.management.cattle.io` could inject a foreign identity provider principal into any account, so that the next login by the owner of that principal was bound to the victim's account and inherited its role bindings. This issue affects Rancher: before 2.15.1.
