CVE-2026-40997
SOAP security faults leak Spring Security account state
Description

Several Spring WS integration paths with Spring Security could surface detailed account state (for example locked or disabled user semantics) to remote SOAP clients through exception messages or callback outcomes, instead of failing with generic authentication errors. That behavior assists remote attackers in distinguishing valid accounts from invalid ones and inferring lifecycle state. Affected versions: Spring Web Services 5.0.0 through 5.0.1; 4.1.0 through 4.1.3; 4.0.0 through 4.0.18; 3.1.0 through 3.1.8.

    Action Type Old Value New Value
    Added Translation Title: Spring Web Services, Description: Varios caminos de integración de Spring WS con Spring Security podrían exponer el estado detallado de la cuenta (por ejemplo, semántica de usuario bloqueado o deshabilitado) a clientes SOAP remotos a través de mensajes de excepción o resultados de retrollamada, en lugar de fallar con errores genéricos de autenticación. Ese comportamiento ayuda a los atacantes remotos a distinguir cuentas válidas de inválidas y a inferir el estado del ciclo de vida. Versiones afectadas: Spring Web Services 5.0.0 hasta 5.0.1; 4.1.0 hasta 4.1.3; 4.0.0 hasta 4.0.18; 3.1.0 hasta 3.1.8.
