CVE-2026-109187

HIGH 7.1

Published 2026-10-12 · Last modified 2026-10-14

jshERP through 3.6 contains an information disclosure vulnerability that allows any authenticated user to read platform-wide configuration secrets via the getInfoByKey handler of PlatformConfigController. Low-privilege users of any tenant can request arbitrary platformKey values such as email_auth_code or activation_code to obtain SMTP authorization codes and activation secrets, because only aliOss and weixin keys are blocked.
