### 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` values the suite accepts (for example rsa-sha256 under Basic256Sha256) while declaring a per-reference `DigestMethod` the suite rejects (for example http://www.w3.org/2000/09/xmldsig#sha1). The signature is then verified where it permits SHA-1 digests, and the message is accepted. ### Patches Fixed in CoreWCF v1.8.1 and v1.9.1 ### Workarounds None
Update CoreWCF.Primitives to 1.8.1; CoreWCF.Primitives to 1.9.1 if you use the affected versions. Test the change in a non-production environment first.

AI coding agents often install or upgrade packages automatically in nuget. A low vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
