{"cve":"CVE-2026-34453","nvd":{"published":"2026-03-31T22:16:20.483","modified":"2026-07-24T21:10:00.143","status":"Analyzed","description":"SiYuan is a personal knowledge management system. Prior to version 3.6.2, the publish service exposes bookmarked blocks from password-protected documents to unauthenticated visitors. In publish/read-only mode, /api/bookmark/getBookmark filters bookmark results by calling FilterBlocksByPublishAccess(nil, ...). Because the filter treats a nil context as authorized, it skips the publish password check and returns bookmarked blocks from documents configured as Protected. As a result, anyone who can access the publish service can retrieve content from protected documents without providing the required password, as long as at least one block in the document is bookmarked. This issue has been patched in version 3.6.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-863"],"references":["https://github.com/siyuan-note/siyuan/issues/17246","https://github.com/siyuan-note/siyuan/releases/tag/v3.6.2","https://github.com/siyuan-note/siyuan/security/advisories/GHSA-c77m-r996-jr3q","https://github.com/siyuan-note/siyuan/security/advisories/GHSA-c77m-r996-jr3q"],"products":["b3log:siyuan"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-34453","score":0.01227,"percentile":0.68863,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-c77m-r996-jr3q","url":"https://osv.dev/vulnerability/GHSA-c77m-r996-jr3q","summary":"SiYuan: Unauthenticated Access to Password-Protected Bookmarks via /api/bookmark/getBookmark","modified":"2026-06-25T19:56:09.070907041Z","packages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","ranges":["<3.6.2"],"fixed":["3.6.2"]}]},{"id":"GO-2026-5318","url":"https://osv.dev/vulnerability/GO-2026-5318","summary":"SiYuan: Unauthenticated Access to Password-Protected Bookmarks via /api/bookmark/getBookmark in github.com/siyuan-note/siyuan/kernel","modified":"2026-06-25T19:45:28.752947513Z","packages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
