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

Published Jun 11, 2026 · Updated Jun 23, 2026 · Assigned by vmware

Description

Wss4jSecurityInterceptor defaulted allowRSA15KeyTransportAlgorithm to true, overriding Apache WSS4J's safer default for validation RequestData. Inbound WS-Security decryption could therefore accept RSA PKCS#1 v1.5 (rsa-1_5) encrypted key material unless operators explicitly reconfigured the flag.
