An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-44670 exists.\n\nAffected packages and fixed versions:\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions; fixed in 0.0.0-20260512140701-d7b77d945e0d\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions; fixed in 0.0.0-20260512140701-d7b77d945e0d\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions; fixed in 0.0.0-20260512140701-d7b77d945e0d\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-44670/ (Markdown: https://insights.sbomify.com/CVE-2026-44670/index.md)","id":"CVE-2026-44670","markdown":"https://insights.sbomify.com/CVE-2026-44670/index.md","name":"CVE-2026-44670","record":{"aliases":["GHSA-2h64-c999-c9r6","GO-2026-4992"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SiYuan knowledge management","requires_auth":"none","summary":"Stored XSS in SiYuan allows remote code execution via Electron renderer due to unsafe HTML injection and insecure browser settings.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"}],"description":"SiYuan is an open-source personal knowledge management system. 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.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"SiYuan: Stored XSS via Attribute View name to Electron renderer RCE in SiYuan","id":"CVE-2026-44670","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"ZITADEL: LDAP Filter Injection in Login Flow","id":"CVE-2026-44671"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20260512140701-d7b77d945e0d"],"introduced":["0"],"last_affected":[],"package":"github.com/siyuan-note/siyuan/kernel","purl":null,"source":"GHSA-2h64-c999-c9r6"},{"ecosystem":"Go","fixed":["0.0.0-20260512140701-d7b77d945e0d"],"introduced":["0"],"last_affected":[],"package":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","source":"GHSA-2h64-c999-c9r6"},{"ecosystem":"Go","fixed":["0.0.0-20260512140701-d7b77d945e0d"],"introduced":["0"],"last_affected":[],"package":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","source":"GO-2026-4992"}],"prev":{"headline":"Faction: Stored XSS in Assessment Attachment Filename Preview Rendering","id":"CVE-2026-44669"},"products":["siyuan"],"published":"2026-05-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-15","vendors":["siyuan-note"]},"summary":"Stored XSS in SiYuan allows remote code execution via Electron renderer due to unsafe HTML injection and insecure browser settings.","url":"https://insights.sbomify.com/CVE-2026-44670/"}
