UBUNTU-CVE-2026-40994 (CVE-2026-40994)

Vulnerability from osv_ubuntu – Published: 2026-06-11 07:16 – Updated: 2026-06-17 04:28 – Source website

Details

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.

Severity
