CVE-2026-40996

CVE-2026-40996 affects Spring Web Services where Wss4jSecurityInterceptor incorrectly defaults allowRSA15KeyTransportAlgorithm to true, overriding Apache WSS4J’s safer validation behavior for RequestData. This could allow RSA PKCS#1 v1.5 (rsa-1_5) encrypted key material in inbound WS-Security dec...

CVE-2026-40996 Inbound WS-Security allows RSA PKCS#1 v1.5 key transport by default

Wss4jSecurityInterceptor defaulted allowRSA15KeyTransportAlgorithm to true, overriding Apache WSS4J's safer default for validation RequestData. Inbound WS-Security decryption could therefore accept RSA PKCS1 v1.5 rsa-15 encrypted key material unless operators explicitly reconfigured the flag...
