Versions 5.5.4 and below allow the use of WcfProxy. WcfProxy uses the now-obsolete NetDataContractSerializer (NDCS) and is vulnerable to remote code execution during deserialization. This vulnerability is fixed in version 6.0.0. To workaround this issue, remove the WcfProxy in data portal configurations.","state":0,"publishedAt":"2025-12-09T03:18:37.698+00:00","modifiedAt":"2025-12-09T15:15:06.46+00:00","affected":[{"ecosystem":"Vendor product","name":"csla","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"MarimerLLC\",\n                    \"product\": \"csla\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 6.0.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U","score":7.2,"severity":"HIGH"}],"references":["https://github.com/MarimerLLC/csla/security/advisories/GHSA-wq34-7f4g-953v","https://github.com/MarimerLLC/csla/issues/4001","https://github.com/MarimerLLC/csla/pull/4018"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-66631","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-66631","identifiers":["CVE-2025-66631"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
