Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-85169 in the wild and no public exploit code.\n\nAffected product: N8n N8n. 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-2026-85169/ (Markdown: https://insights.sbomify.com/CVE-2026-85169/index.md)","id":"CVE-2026-85169","markdown":"https://insights.sbomify.com/CVE-2026-85169/index.md","name":"CVE-2026-85169","record":{"aliases":["GHSA-733v-xpr6-gwgq","GHSA-9x83-43r8-5hwc","MINI-3fpp-j2w5-mcr3"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"n8n workflow automation","requires_auth":"low_privilege","summary":"An attacker with workflow-build privileges can escape the expression sandbox to execute arbitrary code in the n8n process.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"n8n","vendor":"n8n"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/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"}],"description":"n8n versions before 1.123.73, 2.35.4, and 2.36.2 contain an expression sandbox escape in the $fromAI handler. $fromAI resolved a caller-supplied placeholder name without requiring it to be an own property and admitted reserved keys; against a primitive input value it returned a live host-prototype reference.
