Prior to 3.6.5, the fix for CVE-2026-30869 only added a denylist check (IsSensitivePath) but did not address the root cause — a redundant url.PathUnescape() call in serveExport(). An authenticated attacker can use double URL encoding (%252e%252e) to traverse directories and read arbitrary workspace files including the full SQLite database (siyuan.db), kernel log, and all user documents. This vulnerability is fixed in 3.6.5.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":null,"cwes":["CWE-22"],"references":["https://github.com/siyuan-note/siyuan/commit/bb481e1290c4a34255652ede85a546504505d2a7","https://github.com/siyuan-note/siyuan/releases/tag/v3.6.5","https://github.com/siyuan-note/siyuan/security/advisories/GHSA-hjh7-r5w8-5872","https://github.com/siyuan-note/siyuan/security/advisories/GHSA-hjh7-r5w8-5872"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-41894","score":0.00374,"percentile":0.3143,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hjh7-r5w8-5872","url":"https://osv.dev/vulnerability/GHSA-hjh7-r5w8-5872","summary":"SiYuan: Path Traversal via Double URL Encoding in `/export/` Endpoint (Incomplete Fix Bypass for CVE-2026-30869)","modified":"2026-06-25T23:11:45.062615054Z","packages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","ranges":["<3.6.5"],"fixed":["3.6.5"]}]},{"id":"GO-2026-5429","url":"https://osv.dev/vulnerability/GO-2026-5429","summary":"SiYuan: Path Traversal via Double URL Encoding in `/export/` Endpoint (Incomplete Fix Bypass for CVE-2026-30869) in github.com/siyuan-note/siyuan/kernel","modified":"2026-06-25T23:01:09.942014360Z","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).
