CVE-2026-54773

CoreWCF is a port of the service side of Windows Communication Foundation WCF to .NET Core. Prior to 1.8.1 and 1.9.1, CoreWCF WS-Security signature verification performs a document-wide ds:Signature lookup, allowing an unauthenticated remote attacker to place a SOAP header before wsse:Security an...

CVE-2026-54783 CoreWCF: XML Signature Wrapping in WS-Security endorsing/supporting signature verification allows replay of captured signed messages

CoreWCF is a port of the service side of Windows Communication Foundation WCF to .NET Core. Prior to 1.8.1 and 1.9.1, CoreWCF WS-Security endorsing and supporting signature verification does not ensure the selected ds:Signature covers the expected Security header target, allowing an attacker with...

CVE-2026-54783: Authentication Bypass by Capture-replay

CoreWCF is a port of the service side of Windows Communication Foundation WCF to .NET Core. Prior to 1.8.1 and 1.9.1, CoreWCF WS-Security endorsing and supporting signature verification does not ensure the selected ds:Signature covers the expected Security header target, allowing an attacker with...

CVE-2026-54773: Improper Verification of Cryptographic Signature

CoreWCF is a port of the service side of Windows Communication Foundation WCF to .NET Core. Prior to 1.8.1 and 1.9.1, CoreWCF WS-Security signature verification performs a document-wide ds:Signature lookup, allowing an unauthenticated remote attacker to place a SOAP header before wsse:Security an...

CVE-2026-54780: Use of a Broken or Risky Cryptographic Algorithm

CoreWCF is a port of the service side of Windows Communication Foundation WCF to .NET Core. Prior to 1.8.1 and 1.9.1, the CoreWCF WS-Security 1.0 receive pipeline validates ds:SignedInfo SignatureMethod against the configured SecurityAlgorithmSuite but does not validate each ds:Reference...

GHSA-GQV6-PWCG-87R8 CoreWCF: XML Signature Wrapping in WS-Security endorsing/supporting signature verification allows replay of captured signed messages

Impact The attacker, with one captured signed SOAP envelope from a victim and no other privileges, can invoke arbitrary operations on the service as the victim principal for the lifetime of the captured signing key. There is no rate limit on replays. The DetectReplays setting on transport-securit...

Improper Verification of Cryptographic Signature

Overview CoreWCF.Primitives is a port of the service side of Windows Communication Foundation WCF to .NET Core. The goal of this project is to enable existing WCF services to move to .NET Core. Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in...

CoreWCF: WS-Security Reference DigestMethod Algorithm-Suite Bypass

Impact CoreWCF’s WS-Security 1.0 receive pipeline validates the SignatureMethod of an incoming ds:SignedInfo against the configured SecurityAlgorithmSuite, but does not validate the DigestMethod declared on each ds:Reference. As a result, a sender can populate ds:SignedInfo with SignatureMethod...

CoreWCF: WS-Security signature substitution via document-wide Signature lookup

Impact An unauthenticated remote attacker who can place a SOAP header lexically before wsse:Security can embed a ds:Signature of their choosing inside that header and cause the server to verify the attacker-supplied signature instead of the one carried in the security header. Preconditions...

Replay Attack

Spring Web Services is vulnerable to Replay Attack. The vulnerability is due to Wss4jSecurityInterceptor not consistently applying Apache WSS4J ReplayCache instances during inbound WS-Security validation. As a result, replay protection for UsernameToken nonces, creation timestamps, Timestamp...

Security Bulletin: IBM WebSphere Application Server is affected by a remote code execution vulnerability (CVE-2026-9319)

Summary IBM WebSphere Application Server is affected by a remote code execution vulnerability when using JAX-WS endpoints with WS-Security. Vulnerability Details CVEID:CVE-2026-9319 DESCRIPTION: IBM WebSphere Application Server 9.0, and 8.5 is vulnerable to potential remote code execution due to...

Spring Web Services: Wss4jSecurityInterceptor disables WS-I BSP validation by default

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...

GHSA-P7QJ-2Q5W-F9R7 Spring Web Services: 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...
