{"id":"GHSA-q6g5-m978-c6v9","summary":"Duplicate Advisory: Publish-boundary bypass via WebSocket broadcast: anonymous readers receive a live unfiltered feed of all edits including protected/forbidden documents (publish mode)","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-mw8r-mw84-88v2. This link is maintained to preserve external references.\n\n## Original Description\nSiYuan versions before v3.7.4 contain a publish-boundary bypass vulnerability in WebSocket broadcast sessions that allows anonymous readers to receive unfiltered edits. Attackers can establish a WebSocket connection to the publish surface and passively receive real-time content events including password-protected and forbidden documents without authentication.","modified":"2026-09-03T22:45:04.775246472Z","published":"2026-08-14T12:31:24Z","withdrawn":"2026-09-03T22:30:11Z","database_specific":{"cwe_ids":["CWE-862"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2026-09-03T22:30:11Z","nvd_published_at":"2026-08-14T12:16:43Z"},"references":[{"type":"WEB","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-mw8r-mw84-88v2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72810"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/siyuan-before-publish-boundary-bypass-via-websocket"}],"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":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-q6g5-m978-c6v9/GHSA-q6g5-m978-c6v9.json","last_known_affected_version_range":"\u003c 3.7.4"}}],"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"}]}
