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-2026-44588 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 0.0.0-20260421031503-96dfe0bea474; no fix listed\n- github.com/siyuan-note/siyuan/kernel (Go): affected all versions up to 0.0.0-20260421031503-96dfe0bea474; 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-2026-44588/ (Markdown: https://insights.sbomify.com/CVE-2026-44588/index.md)","id":"CVE-2026-44588","markdown":"https://insights.sbomify.com/CVE-2026-44588/index.md","name":"CVE-2026-44588","record":{"aliases":["GHSA-25rp-h46x-2hjm","GO-2026-4993"],"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":"An XSS vulnerability in SiYuan allows attackers to execute arbitrary code via crafted document titles due to improper decoding in tooltip rendering.","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:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"},{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"SiYuan is an open-source personal knowledge management system. Prior to 3.7.0,  he tooltip mouseover handler in app/src/block/popover.ts reads aria-label via getAttribute and passes it through decodeURIComponent before assigning to messageElement.innerHTML in app/src/dialog/tooltip.ts:41. The encoder used at the producer side, escapeAriaLabel in app/src/util/escape.ts:19-25, only handles HTML special characters (\", ', \u003c, literal \u0026lt;) — it leaves %XX URL-escapes untouched. So a doc title containing %3Cimg src=x onerror=...%3E round-trips through escapeAriaLabel and the HTML attribute layer unmodified. Then decodeURIComponent on the consumer side converts %3C to a literal \u003c character (a real \u003c, NOT a character reference). When that string is assigned to innerHTML, the HTML5 tokenizer enters TagOpenState on the literal \u003c, parses the \u003cimg\u003e element, and the onerror handler fires. Because the renderer runs with nodeIntegration: true, contextIsolation: false, webSecurity: false (app/electron/main.js:407-411), require('child_process') is reachable from the injected handler, escalating to arbitrary 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: URL-encoded title bypasses `escapeAriaLabel`, decoded by `decodeURIComponent` into a tooltip-XSS","id":"CVE-2026-44588","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"nuxt-og-image SSRF — bypass of GHSA-pqhr-mp3f-hrpp / v6.2.5 fix (IPv6 + redirect)","id":"CVE-2026-44589"},"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-2026-4993"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.0.0-20260421031503-96dfe0bea474"],"package":"github.com/siyuan-note/siyuan/kernel","purl":null,"source":"GHSA-25rp-h46x-2hjm"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["0.0.0-20260421031503-96dfe0bea474"],"package":"github.com/siyuan-note/siyuan/kernel","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel","source":"GHSA-25rp-h46x-2hjm"}],"prev":{"headline":"CarrierWave has a denylisted_content_type bypass via Unescaped Regex Metacharacters","id":"CVE-2026-44587"},"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":"An XSS vulnerability in SiYuan allows attackers to execute arbitrary code via crafted document titles due to improper decoding in tooltip rendering.","url":"https://insights.sbomify.com/CVE-2026-44588/"}
