Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Spring Web Services (spring-ws-security) versions 5.0.0 through 5.0.1, 4.1.0 through 4.1.3, 4.0.0 through 4.0.18, and 3.1.0 through 3.1.8 disable WS-I Basic Security Profile enforcement in Wss4jSecurityInterceptor by default, so inbound messages that violate BSP rules can be accepted. The source gives few details on the exact attack. Upgrade spring-ws-security to 5.0.2 or 4.1.4, or to a later release in the same line.
