What is CVE-2026-40994?

Wss4jSecurityInterceptor initialized its BSP (WS-I Basic Security Profile) compliance flag so that inbound validation disabled WSS4J BSP enforcement on RequestData. Services that validate WS-Security on the network could therefore accept messages that violate BSP rules, weakening protocol-level checks.

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.

Affected Version(s)

Spring Web Services 5.0.0 < 5.0.2

Spring Web Services 4.1.0 < 4.1.4

Spring Web Services 4.0.0 < 4.0.19
