CVE-2026-59853Public exploitNetwork attack vector

Private saved-search disclosure via missing publish filter

Published Jul 9, 2026 · Updated Jul 9, 2026

Missing authorization in SiYuan before 3.7.1 allows remote authenticated users to read private saved-search metadata through a publish endpoint. The /api/storage/getCriteria handler returns model.GetCriteria() directly, so Reader requests receive unfiltered criteria.json entries instead of publish-access-filtered results. A publish-mode Reader session is required, although anonymous publishing can supply that role; exposure is limited to paths, identifiers, and search or replace terms.
