CVE-2026-41000Network attack vector

Authentication replay via unwired WSS4J caches

Published Jun 11, 2026 · Updated Jun 11, 2026

Authentication replay in Spring Web Services allows remote attackers to reuse accepted WS-Security material in repeated SOAP messages. Wss4jSecurityInterceptor fails to place configured WSS4J ReplayCache instances into RequestData, so validation skips nonce, timestamp, and SAML one-time-use replay checks. Exposure requires a network-reachable SOAP service that validates those constructs and expects the interceptor's configured caches to reject still-valid repeated material.
