Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-56265 exists.\n\nAffected packages and fixed versions:\n- @n8n/n8n-nodes-langchain (npm): affected all versions; fixed in 1.107.0\n- @n8n/n8n-nodes-langchain (npm): affected all versions; fixed in 1.107.0\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-2025-56265/ (Markdown: https://insights.sbomify.com/CVE-2025-56265/index.md)","id":"CVE-2025-56265","markdown":"https://insights.sbomify.com/CVE-2025-56265/index.md","name":"CVE-2025-56265","record":{"aliases":["GHSA-v2x8-97xq-8xrr"],"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":"Attackers can execute arbitrary code by uploading a crafted HTML file to the Chat Trigger component in N8N.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"n8n","vendor":"n8n"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"An arbitrary file upload vulnerability in the Chat Trigger component of N8N v1.95.3, v1.100.1, and v1.101.1 allows attackers to execute arbitrary code via uploading a crafted HTML file.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"N8N's Chat Trigger component is vulnerable to XSS","id":"CVE-2025-56265","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"n8n:n8n","products":["n8n:n8n"],"type":"file_upload","year":"2025"},"n_packages":2,"n_references":3,"next":{"headline":"Other in n/a","id":"CVE-2025-56266"},"packages":[{"ecosystem":"npm","fixed":["1.107.0"],"introduced":["0"],"last_affected":[],"package":"@n8n/n8n-nodes-langchain","purl":null,"source":"GHSA-v2x8-97xq-8xrr"},{"ecosystem":"npm","fixed":["1.107.0"],"introduced":["0"],"last_affected":[],"package":"@n8n/n8n-nodes-langchain","purl":"pkg:npm/%40n8n/n8n-nodes-langchain","source":"GHSA-v2x8-97xq-8xrr"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2025-56264"},"products":["n/a"],"published":"2025-09-08","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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-09-08","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code by uploading a crafted HTML file to the Chat Trigger component in N8N.","url":"https://insights.sbomify.com/CVE-2025-56265/"}
