Versions 3.6.0 and below render package metadata fields (displayName, description) using template literals without HTML escaping. A malicious package author can inject arbitrary HTML/JavaScript into these fields, which executes automatically when any user browses the Bazaar page. Because SiYuan's Electron configuration enables nodeIntegration: true with contextIsolation: false, this XSS escalates directly to full Remote Code Execution on the victim's operating system — with zero user interaction beyond opening the marketplace tab. This issue has been fixed in version 3.6.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","score":9.0},"cwes":["CWE-79"],"references":["https://github.com/siyuan-note/siyuan/security/advisories/GHSA-mvpm-v6q4-m2pf","https://github.com/siyuan-note/siyuan/security/advisories/GHSA-mvpm-v6q4-m2pf"],"products":["b3log:siyuan"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33067","score":0.00559,"percentile":0.46579,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-mvpm-v6q4-m2pf","url":"https://osv.dev/vulnerability/GHSA-mvpm-v6q4-m2pf","summary":"SiYuan has Stored XSS to RCE via Unsanitized Bazaar Package Metadata","modified":"2026-03-23T18:56:22.398411Z","packages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","ranges":["<0.0.0-20260317012524-fe4523fff2c8"],"fixed":["0.0.0-20260317012524-fe4523fff2c8"]}]},{"id":"GO-2026-4747","url":"https://osv.dev/vulnerability/GO-2026-4747","summary":"SiYuan has Stored XSS to RCE via Unsanitized Bazaar Package Metadata in github.com/siyuan-note/siyuan/kernel","modified":"2026-03-23T18:45:15.239026Z","packages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","ranges":["<0.0.0-20260317012524-fe4523fff2c8"],"fixed":["0.0.0-20260317012524-fe4523fff2c8"]}]}],"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).
