CVE-2026-41694

EUVD-2026-35889
Since Spring Security SAML decrypts SAML Responses as well as elements of SAML LogoutRequests and LogoutResponses without requiring a valid signature, attackers may be able to craft these SAML payloads and use the Service Provider as a decryption oracle.

Spring Security 5.7.0 through 5.7.23; 5.8.0 through 5.8.25; 6.3.0 through 6.3.16; 6.4.0 through 6.4.16; 6.5.0 through 6.5.10; 7.0.0 through 7.0.5.
