Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-86082 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- n8n (npm): affected all versions; fixed in 1.123.76\n- n8n (npm): affected all versions; fixed in 1.123.76\n- n8n (npm): affected from 2.0.0; fixed in 2.37.7\n- n8n (npm): affected from 2.0.0; fixed in 2.37.7\n- n8n (npm): affected from 2.38.0; fixed in 2.38.2\n- n8n (npm): affected from 2.38.0; fixed in 2.38.2\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-2026-86082/ (Markdown: https://insights.sbomify.com/CVE-2026-86082/index.md)","id":"CVE-2026-86082","markdown":"https://insights.sbomify.com/CVE-2026-86082/index.md","name":"CVE-2026-86082","record":{"aliases":["GHSA-34ff-336r-5q23","MINI-2328-p6xq-vmvp","ROOT-APP-NPM-CVE-2026-86082"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"n8n workflow automation","requires_auth":"low_privilege","summary":"Attackers can bypass domain restrictions in the OpenAI Chat Model node to send credentials to arbitrary hosts via the model-search endpoint.","user_interaction":"not_required","vuln_class":"ssrf"},"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:L/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"n8n is an open source workflow automation platform.
