CVE-2026-22734: Authentication bypass by spoofing vulnerability

Cloud Foundry UUA is vulnerable to a bypass that allows an attacker to obtain a token for any user and gain access to UAA-protected systems. This vulnerability exists when SAML 2.0 bearer assertions are enabled for a client, as the UAA accepts SAML 2.0 bearer assertions that are neither signed nor encrypted. This issue affects UUA from v77.30.0 to v78.7.0 (inclusive) and it affects CF Deployment from v48.7.0 to v54.14.0 (inclusive).
