Prior to 3.7.0, the patch for CVE-2026-41894 (\"Path Traversal via Double URL Encoding\") sanitized the /export/ route but the identical root cause remains in the /assets/*path route. In publish mode (anonymous read-only HTTP endpoint, default port 6808), an unauthenticated remote attacker can read arbitrary files inside WorkspaceDir — including conf/conf.json (which contains the AccessAuthCode SHA256 hash, API token, and sync keys), temp/siyuan.db, temp/blocktree.db, and siyuan.log — by double-URL-encoding .. segments. This vulnerability is fixed in 3.7.0.","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-22","CWE-23","CWE-1188"],"references":["https://github.com/siyuan-note/siyuan/security/advisories/GHSA-p4m3-mgmm-c664","https://github.com/siyuan-note/siyuan/security/advisories/GHSA-p4m3-mgmm-c664"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-54066","score":0.02386,"percentile":0.8381,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-p4m3-mgmm-c664","url":"https://osv.dev/vulnerability/GHSA-p4m3-mgmm-c664","summary":"SiYuan: Path Traversal via Double URL Encoding in /assets/*path (publish mode arbitrary   file─read), Incomplete fix of CVE-2026-41894 ","modified":"2026-07-21T19:19:05.958413892Z","packages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","ranges":["<0.0.0-20260628153353-2d5d72223df4"],"fixed":["0.0.0-20260628153353-2d5d72223df4"]}]},{"id":"GO-2026-5964","url":"https://osv.dev/vulnerability/GO-2026-5964","summary":"SiYuan: Path Traversal via Double URL Encoding in /assets/*path (publish mode arbitrary file─read), Incomplete fix of CVE-2026-41894 in github.com/siyuan-note/siyuan/kernel","modified":"2026-07-21T19:15:30.615760143Z","packages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","ranges":["<0.0.0-20260628153353-2d5d72223df4"],"fixed":["0.0.0-20260628153353-2d5d72223df4"]}]}],"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).
