Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-45732 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- n8n (npm): affected all versions; fixed in 1.123.43\n- n8n (npm): affected all versions; fixed in 1.123.43\n- n8n (npm): affected from 2.0.0-rc.0; fixed in 2.20.7\n- n8n (npm): affected from 2.0.0-rc.0; fixed in 2.20.7\n- n8n (npm): affected from 2.21.0; fixed in 2.21.1\n- n8n (npm): affected from 2.21.0; fixed in 2.21.1\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-2026-45732/ (Markdown: https://insights.sbomify.com/CVE-2026-45732/index.md)","id":"CVE-2026-45732","markdown":"https://insights.sbomify.com/CVE-2026-45732/index.md","name":"CVE-2026-45732","record":{"aliases":["GHSA-6h4j-wcr9-2vg7","MINI-qvg8-g6p3-6q7f","ROOT-APP-NPM-CVE-2026-45732"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"n8n workflow automation","requires_auth":"low_privilege","summary":"Authenticated users with read-only access can overwrite OAuth tokens, enabling data exfiltration and persistent takeover of shared integrations in n8n.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"n8n","vendor":"n8n"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, the OAuth1 and OAuth2 credential reconnect endpoints authorized access using credential:read rather than credential:update. An authenticated user with read-only access to a shared credential could initiate an OAuth reconnect flow and overwrite the stored token material for that credential with tokens bound to an external account they control. Workflows relying on the affected credential would subsequently execute under the attacker's OAuth identity, enabling data exfiltration to attacker-controlled external services and persistent takeover of shared integrations.
