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.\n\n### Patches\nFixed in CoreWCF v1.8.1 and v1.9.1\n\n### Workarounds\nNone","affected":[{"package":{"name":"CoreWCF.Primitives","ecosystem":"NuGet","purl":"pkg:nuget/CoreWCF.Primitives"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.8.1"}]}],"versions":["0.1.0","0.1.0-preview","0.1.0-preview-2","0.2.0","0.2.1","0.3.0","0.3.1","0.3.2","0.4.0","1.0.0","1.0.0-preview1","1.0.0-preview2","1.0.1","1.0.2","1.1.0","1.1.1","1.2.0","1.2.1","1.3.0","1.3.1","1.3.2","1.4.0","1.4.0-preview1","1.4.1","1.4.2","1.5.0","1.5.0-preview1","1.5.1","1.5.2","1.6.0","1.7.0","1.8.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-4v55-cpmv-3vcm/GHSA-4v55-cpmv-3vcm.json"}},{"package":{"name":"CoreWCF.Primitives","ecosystem":"NuGet","purl":"pkg:nuget/CoreWCF.Primitives"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.9.0"},{"fixed":"1.9.1"}]}],"versions":["1.9.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-4v55-cpmv-3vcm/GHSA-4v55-cpmv-3vcm.json"}}],"references":[{"type":"WEB","url":"https://github.com/CoreWCF/CoreWCF/security/advisories/GHSA-4v55-cpmv-3vcm"},{"type":"PACKAGE","url":"https://github.com/CoreWCF/CoreWCF"}],"database_specific":{"cwe_ids":["CWE-327","CWE-757"],"github_reviewed":true,"github_reviewed_at":"2026-06-19T20:47:04Z","nvd_published_at":null,"severity":"LOW"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"}]} |
