In CloudStack environments where SAML authentication is enabled, an attacker that initiates CloudStack SAML single sign-on authentication can bypass SAML authentication by submitting a spoofed SAML response with no signature and known or guessed username and other user details of a SAML-enabled CloudStack user-account. In such environments, this can result in a complete compromise of the resources owned and/or accessible by a SAML enabled user-account.\n\nAffected users are recommended to disable the SAML authentication plugin by setting the \"saml2.enabled\" global setting to \"false\", or upgrade to version 4.18.2.2, 4.19.1.0 or later, which addresses this issue.","published":"2024-07-19T11:15:03.000Z","lastModified":"2026-06-17T07:47:17.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-290"],"affected":["apache/cloudstack"],"epss":{"score":0.1776,"percentile":0.97167,"date":"2026-11-03","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 17.8%, higher than 97% of all known CVEs.
