Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-65597 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- n8n (npm): affected all versions; fixed in 1.123.64\n- n8n (npm): affected all versions; fixed in 1.123.64\n- n8n (npm): affected from 2.0.0-rc.0; fixed in 2.29.8\n- n8n (npm): affected from 2.0.0-rc.0; fixed in 2.29.8\n- n8n (npm): affected from 2.30.0; fixed in 2.30.1\n- n8n (npm): affected from 2.30.0; fixed in 2.30.1\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-2026-65597/ (Markdown: https://insights.sbomify.com/CVE-2026-65597/index.md)","id":"CVE-2026-65597","markdown":"https://insights.sbomify.com/CVE-2026-65597/index.md","name":"CVE-2026-65597","record":{"aliases":["GHSA-p3rg-hrf9-w9gj","MINI-2g7g-v6gp-88qm","ROOT-APP-NPM-CVE-2026-65597"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"n8n workflow automation","requires_auth":"low_privilege","summary":"An attacker with member privileges can execute arbitrary scripts in the victim's browser via unsandboxed HTML preview, potentially hijacking sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"n8n","vendor":"n8n"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"n8n before 1.123.64, 2.x before 2.29.8, and before 2.30.1 contains a DOM-based cross-site scripting vulnerability in the HTML preview, which renders execution output into an iframe srcdoc without the sandbox attribute.
