In versions 3.6.0 and below, POST /api/import/importSY and POST /api/import/importZipMd write uploaded archives to a path derived from the multipart filename field without sanitization, allowing an admin to write files to arbitrary locations outside the temp directory - including system paths that enable RCE. This can lead to aata destruction by overwriting workspace or application files, and for Docker containers running as root (common default), this grants full container compromise. This issue has been fixed in version 3.6.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","score":9.1},"cwes":["CWE-22","CWE-73"],"references":["https://github.com/siyuan-note/siyuan/commit/5ee00907f0b0c4aca748ce21ef1977bb98178e14","https://github.com/siyuan-note/siyuan/releases/tag/v3.6.1","https://github.com/siyuan-note/siyuan/security/advisories/GHSA-qvvf-q994-x79v"],"products":["b3log:siyuan"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-32749","score":0.00442,"percentile":0.38415,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-qvvf-q994-x79v","url":"https://osv.dev/vulnerability/GHSA-qvvf-q994-x79v","summary":"SiYuan importSY/importZipMd: path traversal via multipart filename enables arbitrary file write","modified":"2026-03-30T13:58:28Z","packages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","ranges":["<=0.0.0-20260313024916-fd6526133bb3"],"fixed":[]}]},{"id":"GO-2026-4707","url":"https://osv.dev/vulnerability/GO-2026-4707","summary":"SiYuan importSY/importZipMd: path traversal via multipart filename enables arbitrary file write in github.com/siyuan-note/siyuan/kernel","modified":"2026-03-26T21:03:00.553336Z","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).
