CVE-2025-23387Network attack vector

SAML CLI login denial via public token deletion

Published Apr 11, 2025 · Updated Apr 11, 2025

Denial of service in SUSE Rancher 2.8.0 through 2.8.12, 2.9.0 through 2.9.6, and 2.10.0 through 2.10.2 allows remote attackers to deny SAML CLI login. The public /v3-public/authTokens collection exposes GET and DELETE methods, so an unauthenticated requester can enumerate and remove randomly named encrypted CLI tokens before the polling client retrieves a value. Only deployments using SAML-based authentication and the Rancher CLI token execution command are affected; the tokens cannot impersonate users, and successful deletion interrupts CLI login.
