CVE-2026-59853: CWE-862: Missing Authorization in siyuan-note siyuan
SiYuan is an open-source personal knowledge management system. Prior to 3.7.1, the /api/storage/getCriteria endpoint returns saved search criteria from data/storage/criteria.json without the publish-access filtering used by sibling storage endpoints, allowing a publish-mode Reader to read private document paths, notebook, document, and block IDs, and search and replace keywords for unpublished documents. This issue is fixed in versions 3.7.1.
