CVE-2026-41000

LOW

3.7

CVSS v3

NVD

Description

Wss4jSecurityInterceptor did not consistently wire Apache WSS4J ReplayCache instances into RequestData for validation-time checks. As a result, protections against replay of UsernameToken nonces and creation timestamps, Timestamp elements, and certain SAML one-time-use semantics could be ineffective even when operators configured a replay cache on the interceptor. 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.
