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...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in PKCS7verify. An attacker supplying a PKCS7 or S/MIME signed message whose SignedData digestAlgorithms field is an empty ASN.1 SET can cause a caller-owned BIO to be freed during verification. A subsequent use of that B...
