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`.","published":"2024-09-19T23:15:12.000Z","lastModified":"2026-06-17T07:56:19.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-74"],"affected":["antfin/sofa-hessian"],"epss":{"score":0.00678,"percentile":0.52138,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.68%).
