## Overview

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

- `spring_web_services < 3.1.9`
- `spring_web_services >= 4.0.0, < 4.0.19`
- `spring_web_services >= 4.1.0, < 4.1.3.1`
- `spring_web_services >= 5.0.0, < 5.0.1.1`

## Remediation

Upgrade past the affected range:

- `spring_web_services 5.0.1.1`
