CVE-2026-59853

MEDIUMPre-NVD 6.56.5
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 85% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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Reader to read private document paths, notebook, document, and block IDs, and search and replace keywords for unpublished documents.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.
