Description

Wss4jSecurityInterceptor initialized its BSP (WS-I Basic Security Profile) compliance flag so that inbound validation disabled WSS4J BSP enforcement on RequestData.

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.
