Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-27494 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- n8n (npm): affected all versions; fixed in 1.123.22\n- n8n (npm): affected all versions; fixed in 1.123.22\n- n8n (npm): affected from 2.0.0; fixed in 2.9.3\n- n8n (npm): affected from 2.0.0; fixed in 2.9.3\n- n8n (npm): affected from 2.10.0; fixed in 2.10.1\n- n8n (npm): affected from 2.10.0; fixed in 2.10.1\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-2026-27494/ (Markdown: https://insights.sbomify.com/CVE-2026-27494/index.md)","id":"CVE-2026-27494","markdown":"https://insights.sbomify.com/CVE-2026-27494/index.md","name":"CVE-2026-27494","record":{"aliases":["GHSA-mmgg-m5j7-f83h"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"n8n workflow automation","requires_auth":"low_privilege","summary":"Authenticated users can escape the Python sandbox to read files or execute code, potentially compromising the host if Task Runners are enabled.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"n8n","vendor":"n8n"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-497","name":"Exposure of Sensitive System Information to an Unauthorized Control Sphere"}],"description":"n8n is an open source workflow automation platform. Prior to versions 2.10.1, 2.9.3, and 1.123.22, an authenticated user with permission to create or modify workflows could use the Python Code node to escape the sandbox. The sandbox did not sufficiently restrict access to certain built-in Python objects, allowing an attacker to exfiltrate file contents or achieve RCE. On instances using internal Task Runners (default runner mode), this could result in full compromise of the n8n host. On instances using external Task Runners, the attacker might gain access to or impact other task executed on the Task Runner. Task Runners must be enabled using `N8N_RUNNERS_ENABLED=true`. The issue has been fixed in n8n versions 2.10.1, 2.9.3, and 1.123.22. Users should upgrade to this version or later to remediate the vulnerability. If upgrading is not immediately possible, administrators should consider the following temporary mitigations. Limit workflow creation and editing permissions to fully trusted users only., and/or disable the Code node by adding `n8n-nodes-base.code` to the `NODES_EXCLUDE` environment variable. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"n8n has Arbitrary File Read via Python Code Node Sandbox Escape","id":"CVE-2026-27494","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"n8n:n8n","products":["n8n:n8n"],"type":"code_injection","year":"2026"},"n_packages":6,"n_references":4,"next":{"headline":"n8n has a Sandbox Escape in its JavaScript Task Runner","id":"CVE-2026-27495"},"packages":[{"ecosystem":"npm","fixed":["1.123.22"],"introduced":["0"],"last_affected":[],"package":"n8n","purl":null,"source":"GHSA-mmgg-m5j7-f83h"},{"ecosystem":"npm","fixed":["1.123.22"],"introduced":["0"],"last_affected":[],"package":"n8n","purl":"pkg:npm/n8n","source":"GHSA-mmgg-m5j7-f83h"},{"ecosystem":"npm","fixed":["2.9.3"],"introduced":["2.0.0"],"last_affected":[],"package":"n8n","purl":null,"source":"GHSA-mmgg-m5j7-f83h"},{"ecosystem":"npm","fixed":["2.9.3"],"introduced":["2.0.0"],"last_affected":[],"package":"n8n","purl":"pkg:npm/n8n","source":"GHSA-mmgg-m5j7-f83h"},{"ecosystem":"npm","fixed":["2.10.1"],"introduced":["2.10.0"],"last_affected":[],"package":"n8n","purl":null,"source":"GHSA-mmgg-m5j7-f83h"},{"ecosystem":"npm","fixed":["2.10.1"],"introduced":["2.10.0"],"last_affected":[],"package":"n8n","purl":"pkg:npm/n8n","source":"GHSA-mmgg-m5j7-f83h"}],"prev":{"headline":"n8n has Unauthenticated Expression Evaluation via Form Node","id":"CVE-2026-27493"},"products":["n8n"],"published":"2026-02-25","related":[{"cvss_score":10,"headline":"n8n Improper Control of Dynamically-Managed Code Resources","id":"CVE-2025-68613","kev_date_added":"2026-03-11","published":"2025-12-19"},{"cvss_score":10,"headline":"n8n is vulnerable to Remote Code Execution via Arbitrary File Write","id":"CVE-2026-21877","kev_date_added":null,"published":"2026-01-08"},{"cvss_score":10,"headline":"n8n Vulnerable to Unauthenticated File Access via Improper Webhook Request Handling","id":"CVE-2026-21858","kev_date_added":null,"published":"2026-01-07"},{"cvss_score":9.9,"headline":"n8n Unsafe Workflow Expression Evaluation Allows Remote Code Execution","id":"CVE-2026-1470","kev_date_added":null,"published":"2026-01-27"},{"cvss_score":9.9,"headline":"n8n Vulnerable to Arbitrary Command Execution in Pyodide based Python Code Node","id":"CVE-2025-68668","kev_date_added":null,"published":"2025-12-26"},{"cvss_score":9.5,"headline":"n8n has Unauthenticated Expression Evaluation via Form Node","id":"CVE-2026-27493","kev_date_added":null,"published":"2026-02-25"},{"cvss_score":9.4,"headline":"n8n: HTTP Request Node Pagination Prototype Pollution to RCE","id":"CVE-2026-44789","kev_date_added":null,"published":"2026-06-23"}],"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":"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-02-26","vendors":["n8n-io"]},"summary":"Authenticated users can escape the Python sandbox to read files or execute code, potentially compromising the host if Task Runners are enabled.","url":"https://insights.sbomify.com/CVE-2026-27494/"}
