Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Spring Web Services (org.springframework.ws:spring-ws-core) 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 are affected. When WS-Addressing uses non-anonymous ReplyTo or FaultTo addresses, Spring WS can open outbound connections to destinations taken from request headers without checking them, allowing server-side request forgery. Upgrade to spring-ws-core 5.0.2 or 4.1.4, or to a later release in your line; the source does not list a workaround for versions 4.0.x or 3.1.x.
