CVE-2025-51743Network attack vector

Unspecified impact via Fastjson deserialization

Published Nov 25, 2025 · Updated Nov 26, 2025

Fastjson deserialization in JSH_ERP 2.3.1 allows remote attackers to cause unspecified impact via the addMaterialCategory endpoint. The endpoint accepts untrusted data for Fastjson deserialization, but public records do not identify the request field, parsing call, or enabled gadget path. No privileges or user interaction are required, and the published assessment covers confidentiality, integrity, and availability.
