{"id":"GHSA-85xq-27m5-59m9","summary":"Duplicate Advisory: SiYuan: Full-content disclosure of publish-disabled documents via getHeading*Transaction endpoints (publish mode): reader-reachable rendered DOM with no publish-access check","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-69mh-gvh4-8gp7. This link is maintained to preserve external references.\n\n## Original Description\nSiYuan versions before v3.7.3 contain an information disclosure vulnerability in the getHeadingDeleteTransaction, getHeadingLevelTransaction, and getHeadingInsertTransaction endpoints that return rendered block DOM without publish-access checks. Anonymous readers or publish RoleReader tokens can supply a heading block ID to read full rendered content of publish-disabled documents that should be restricted.","modified":"2026-09-03T21:30:04.328724258Z","published":"2026-08-03T15:32:47Z","withdrawn":"2026-09-03T21:17:47Z","database_specific":{"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2026-09-03T21:17:47Z","nvd_published_at":"2026-08-03T14:16:28Z","cwe_ids":["CWE-862"]},"references":[{"type":"WEB","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-69mh-gvh4-8gp7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68587"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/siyuan-before-information-disclosure-via-getheading-transaction"}],"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"},{"last_affected":"3.7.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-85xq-27m5-59m9/GHSA-85xq-27m5-59m9.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/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:H/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"}]}
