CVE-2026-89260Network attack vector

File disclosure via unsafe WeChat callback parsing

Published Sep 11, 2026 · Updated Sep 11, 2026

XML external entity injection in MoguBlog 6.2 and earlier allows remote attackers to read local files through the WeChat callback. WechatRestApi.index() passes the raw POST body to SignUtil.xmlToMap(), whose SAXReader resolves attacker-supplied external entities without DTD restrictions. The callback requires no authentication; crafted XML can expose server files or cause outbound HTTP requests, with resolved content returned in error responses.
