Prior to 3.7.0, the kernel stores Attribute View (AV / database) names without any HTML escape, then a render template uses raw strings.ReplaceAll(tpl, \"${avName}\", nodeAvName) to embed the name in HTML before pushing to all clients via WebSocket. Three independent client paths (render.ts:120 → outerHTML, Title.ts:401 → innerHTML, transaction.ts:559 → innerHTML) consume the value without escaping. Because the main BrowserWindow runs nodeIntegration:true, contextIsolation:false, webSecurity:false (app/electron/main.js:407-411), HTML injection in the renderer becomes Node.js code execution. This vulnerability is fixed in 3.7.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.4},"cvss_v3":null,"cwes":["CWE-79","CWE-94","CWE-1188"],"references":["https://github.com/siyuan-note/siyuan/security/advisories/GHSA-2h64-c999-c9r6","https://github.com/siyuan-note/siyuan/security/advisories/GHSA-2h64-c999-c9r6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-44670","score":0.00509,"percentile":0.43463,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-2h64-c999-c9r6","url":"https://osv.dev/vulnerability/GHSA-2h64-c999-c9r6","summary":"SiYuan Affected by Stored XSS via Attribute View Name to Electron Renderer RCE","modified":"2026-06-08T20:11:15Z","packages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","ranges":["<0.0.0-20260512140701-d7b77d945e0d"],"fixed":["0.0.0-20260512140701-d7b77d945e0d"]}]},{"id":"GO-2026-4992","url":"https://osv.dev/vulnerability/GO-2026-4992","summary":"SiYuan Affected by Stored XSS via Attribute View Name to Electron Renderer RCE in github.com/siyuan-note/siyuan/kernel","modified":"2026-05-20T19:30:12.975843054Z","packages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","ranges":["<0.0.0-20260512140701-d7b77d945e0d"],"fixed":["0.0.0-20260512140701-d7b77d945e0d"]}]}],"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).
