The SOFA Hessian protocol uses a blacklist mechanism to restrict deserialization of potentially dangerous classes for security protection. But there is a gadget chain that can bypass the SOFA Hessian blacklist protection mechanism, and this gadget chain only relies on JDK and does not rely on any third-party components. This issue is fixed by an update to the blacklist, users can upgrade to sofahessian version 3.5.5 to avoid this issue. Users unable to upgrade may maintain a blacklist themselves in the directory `external/serialize.blacklist`.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-74"],"references":["https://github.com/sofastack/sofa-hessian/security/advisories/GHSA-c459-2m73-67hj"],"products":["antfin:sofa-hessian"],"source":"nvd","synced_at":"2026-10-19T21:54:38.012257375+00:00"},"epss":{"cve":"CVE-2024-46983","score":0.00678,"percentile":0.52352,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-c459-2m73-67hj","url":"https://osv.dev/vulnerability/GHSA-c459-2m73-67hj","summary":"SOFA Hessian Remote Command Execution (RCE) Vulnerability","modified":"2026-09-10T03:50:18.866569731Z","packages":[{"ecosystem":"Maven","name":"com.alipay.sofa:hessian","purl":"pkg:maven/com.alipay.sofa/hessian","ranges":["<3.5.5"],"fixed":["3.5.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
