CVE-2026-1218Public exploitNetwork attack vector

Server-side entity resolution via initRCForm XML parsing

Published Jan 20, 2026 · Updated Jan 20, 2026

XML external entity injection in Zhiyou ERP 11.0 allows remote authenticated users to make the server resolve attacker-supplied entities. The initRCForm method in RichClientService.class parses XML input without restricting external entity resolution, causing dereferencing of attacker-controlled identifiers. Low-privileged access to the remote RichClientService component is required; the public proof of concept demonstrates entity resolution, but no narrower impact boundary is documented.
