Any signed-in user can exploit it over the network, 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-2026-32751 exists.\n\nAffected packages and fixed versions:\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions; no fix listed\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions up to 0.0.0-20260313024916-fd6526133bb3; no fix listed\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions up to 0.0.0-20260313024916-fd6526133bb3; no fix listed\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-2026-32751/ (Markdown: https://insights.sbomify.com/CVE-2026-32751/index.md)","id":"CVE-2026-32751","markdown":"https://insights.sbomify.com/CVE-2026-32751/index.md","name":"CVE-2026-32751","record":{"aliases":["GHSA-qr46-rcv3-4hq3","GO-2026-4706"],"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":"low_privilege","summary":"Authenticated attackers can inject JavaScript via notebook names, leading to remote code execution on mobile and desktop clients due to unsafe innerHTML usage and Electron configuration.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"siyuan","vendor":"b3log"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"SiYuan is a personal knowledge management system. In versions 3.6.0 and below, the mobile file tree (MobileFiles.ts) renders notebook names via innerHTML without HTML escaping when processing renamenotebook WebSocket events. The desktop version (Files.ts) properly uses escapeHtml() for the same operation. An authenticated user who can rename notebooks can inject arbitrary HTML/JavaScript that executes on any mobile client viewing the file tree. Since Electron is configured with nodeIntegration: true and contextIsolation: false, the injected JavaScript has full Node.js access, escalating stored XSS to full remote code execution. The mobile layout is also used in the Electron desktop app when the window is narrow, making this exploitable on desktop as well. This issue has been fixed in version 3.6.1.","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 Vulnerable to Remote Code Execution via Stored XSS in Notebook Name - Mobile Interface","id":"CVE-2026-32751","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":"b3log:siyuan","products":["b3log:siyuan"],"type":"xss","year":"2026"},"n_packages":3,"n_references":3,"next":{"headline":"FreeScout: Broken Access Control in ThreadPolicy — Any User Can Read/Edit All Customer Messages","id":"CVE-2026-32752"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","source":"GO-2026-4706"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.0.0-20260313024916-fd6526133bb3"],"package":"github.com/siyuan-note/siyuan/kernel","purl":null,"source":"GHSA-qr46-rcv3-4hq3"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.0.0-20260313024916-fd6526133bb3"],"package":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","source":"GHSA-qr46-rcv3-4hq3"}],"prev":{"headline":"SiYuan importStdMd: unvalidated localPath imports arbitrary host directories as persistent notes","id":"CVE-2026-32750"},"products":["siyuan"],"published":"2026-03-19","related":[{"cvss_score":9.9,"headline":"SiYuan has an Arbitrary File Read in its Desktop Publish Service","id":"CVE-2026-32938","kev_date_added":null,"published":"2026-03-20"},{"cvss_score":9.8,"headline":"SiYuan has Arbitrary Document Reading within the Publishing Service","id":"CVE-2026-33669","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":9.8,"headline":"SiYuan has directory traversal within its publishing service","id":"CVE-2026-33670","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":9.8,"headline":"SiYuan: Authorization Bypass Allows Arbitrary SQL Execution via Search API","id":"CVE-2026-32767","kev_date_added":null,"published":"2026-03-20"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2024-53504","kev_date_added":null,"published":"2024-11-29"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2024-53505","kev_date_added":null,"published":"2024-11-29"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2024-53506","kev_date_added":null,"published":"2024-11-29"}],"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":"US public information, NVD API terms","name":"NVD"},{"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":"2026-03-24","vendors":["siyuan-note"]},"summary":"Authenticated attackers can inject JavaScript via notebook names, leading to remote code execution on mobile and desktop clients due to unsafe innerHTML usage and Electron configuration.","url":"https://insights.sbomify.com/CVE-2026-32751/"}
