{"id":"GHSA-69jp-f2p8-9vrg","summary":"Duplicate Advisory: 17 block metadata/content endpoints in kernel/api/block.go have zero publish-access filtering, reachable by anonymous publish-mode readers","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-4vpg-gwqq-w44c. This link is maintained to preserve external references.\n\n## Original Description\nSiYuan 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block IDs across the workspace.","modified":"2026-10-02T23:15:06.684891843Z","published":"2026-08-18T12:31:21Z","withdrawn":"2026-10-02T22:56:13Z","database_specific":{"github_reviewed_at":"2026-10-02T22:56:13Z","nvd_published_at":"2026-08-18T12:19:30Z","cwe_ids":["CWE-862"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-4vpg-gwqq-w44c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74904"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/siyuan-before-missing-authorization-via-block-api"}],"affected":[{"package":{"name":"github.com/siyuan-note/siyuan/kernel","ecosystem":"Go","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"last_known_affected_version_range":"\u003c 3.7.4","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-69jp-f2p8-9vrg/GHSA-69jp-f2p8-9vrg.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
