high Tenable Self-Hosted Container Security Plugin ID 472076

Description

 - SiYuan before v3.7.4 is missing authorization checks in 17 block metadata/content endpoints in
 kernel/api/block.go (including getRefText, checkBlockExist, and getBlockBreadcrumb). These handlers are
 gated only by basic authentication (model.CheckAuth) and lack publish-access filtering, allowing anonymous
 publish-mode readers to disclose private block content-derived text, structural metadata, and existence
 information for arbitrary block IDs across the workspace. (CVE-2026-74904)

Update the github.com/siyuan-note/siyuan/kernel library and its related packages to version 0.0.0-20260804015139-bd067a4fe9b2 or later.
