MEDIUM
SiYuan before v3.7.4 Information Disclosure via getAttributeViewFieldViews
Record summary
CVE-2026-72791 has a selected CVSS score of 6.9 (medium).
Description
SiYuan v3.7.4-alpha.1 (a pre-release; the endpoint does not exist in stable v3.7.3 or earlier) contains an information disclosure vulnerability in the /api/av/getAttributeViewFieldViews endpoint. The route is registered with CheckAuth only and applies no publish-access filtering, so reader-role callers can retrieve the complete database view structure — every view's name, icon, layout type, and per-field Hidden flag — for any database whose avID is supplied, regardless of authorization. The issue was introduced by commit acfc02ee8 and fixed in v3.7.4.
