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":"2025-12-09T16:18:22.103+00:00","modifiedAt":"2026-10-07T20:10:01.97+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","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/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":7.2,"severity":"HIGH"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/MarimerLLC/csla/issues/4001","https://github.com/MarimerLLC/csla/pull/4018","https://github.com/MarimerLLC/csla/security/advisories/GHSA-wq34-7f4g-953v"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-66631","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-502"],"productCriteria":["cpe:2.3:a:cslanet:csla_.net:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2025-12-09T16:18:22.103","lastModified":"2026-10-07T20:10:01.970"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
