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-2026-47727 exists.\n\nAffected product: TriliumNext Trilium. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-47727/ (Markdown: https://insights.sbomify.com/CVE-2026-47727/index.md)","id":"CVE-2026-47727","markdown":"https://insights.sbomify.com/CVE-2026-47727/index.md","name":"CVE-2026-47727","record":{"aliases":["GHSA-c26q-6pwv-wf25"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Trilium note-taking app","requires_auth":"none","summary":"Attackers can achieve remote code execution in Trilium by importing a malicious archive that bypasses safe import filters, leading to server-side template injection.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"trilium","vendor":"triliumnotes"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-1336","name":"Improper Neutralization of Special Elements Used in a Template Engine"}],"description":"Trilium is an open-source hierarchical note-taking application. In versions prior to 0.104.0, the default-on \"Safe import\" filter fails to neutralize the shareTemplate relation because that relation is not marked as dangerous, allowing an attacker-supplied import archive to plant a server-side template that leads to remote code execution. The relation is omitted from the built-in list of dangerous attributes, so unlike other code-loading relations it is not disabled on import, and when the victim later publishes the imported note the public share renderer feeds the linked EJS code note's raw bytes into ejs.render, which compiles them in the server's Node process. An unauthenticated request to the shared note then executes the attacker's JavaScript with full access to require, process, the filesystem, and the network. This issue is fixed in version 0.104.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Code injection in Trilium","id":"CVE-2026-47727","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Bugsink: Project scoping missing in sourcemap and debug-file lookup","id":"CVE-2026-47728"},"packages":[],"prev":{"headline":"nebula-mesh: GET /api/v1/audit-log discloses all entries to any operator","id":"CVE-2026-47726"},"products":["Trilium"],"published":"2026-08-27","related":[{"cvss_score":9.3,"headline":"Trilium: Malicious import with GeoMap marker title XSS leads to RCE on the desktop client","id":"CVE-2026-48996","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":9.3,"headline":"Trilium: Note Import to RCE via Mind Elixir dangerouslySetInnerHtml","id":"CVE-2026-53578","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":9.3,"headline":"Trilium: Note Import to RCE via Book Note","id":"CVE-2026-53579","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":8.1,"headline":"Trilium arbitrary file read and denial of service via file:// URLs in the automatic image-download feature","id":"CVE-2026-53580","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":7.5,"headline":"Trilium unauthenticated share-search discloses password-protected and hidden shared notes","id":"CVE-2026-77438","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":7.4,"headline":"Trilium Notes has a Timing Attack Vulnerability in /api/login/sync","id":"CVE-2025-68621","kev_date_added":null,"published":"2026-02-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-09-01","vendors":["TriliumNext"]},"summary":"Attackers can achieve remote code execution in Trilium by importing a malicious archive that bypasses safe import filters, leading to server-side template injection.","url":"https://insights.sbomify.com/CVE-2026-47727/"}
