Summary

SiYuan versions <= v3.7.2 expose the /api/search/searchEmbedBlock endpoint, which passes a client-supplied SQL statement verbatim to the main read-write siyuan.db handle with no single-statement, read-only, or admin restrictions. The endpoint is gated only by CheckAuth, making it reachable by the publish RoleReader token and by anonymous users when publish authentication is disabled. Because the underlying driver executes stacked statements, an attacker can read and modify content across all opened cleartext notebooks (encrypted per-box notebooks are excluded). Fixed in v3.7.3.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
