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 SAML token replay protection is inoperative because DefaultTokenReplayCache.TryAdd does not reject duplicate tokens when DetectReplayedTokens is enabled, allowing a captured token to be reused. This issue is fixed in versions 1.8.1 and 1.9.1.

 https://cve.radiocsirt.org/vuln/ghsa-9jr3-rj99-8jq3 GHSA-9jr3-rj99-8jq3 — CoreWCF: SAML token replay protection is inoperative 2026-10-06T14:07:47.495415+00:00

Affected: NuGet: CoreWCF.Primitives

### Impact When enabling DetectReplayedTokens, a token can be replayed and will be detected despite it being reused.

### Patches Fixed in CoreWCF v1.8.1 and v1.9.1

### Workarounds Provide your own implementation of `ITokenReplayCache` with the correct behavior.
