If a victim opened the credential and interacted with the OAuth authorization button, the injected script would execute in their browser session.\n\n## Patches\nThe issue has been fixed in n8n versions 2.8.0 and 2.6.4. Users should upgrade to one of these versions or later to remediate the vulnerability.\n\n## Workarounds\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Limit credential creation and sharing permissions to fully trusted users only.\n- Restrict access to the n8n instance to trusted users only.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","state":0,"publishedAt":"2026-03-27T18:08:15+00:00","modifiedAt":"2026-07-09T04:11:37.7309158+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.7.0"},{"kind":"fixed","version":"2.8.0"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.6.4"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-364x-8g5j-x2pr","https://github.com/n8n-io/n8n"],"sourceUrl":"https://github.com/advisories/GHSA-364x-8g5j-x2pr","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-364x-8g5j-x2pr","identifiers":["GHSA-364x-8g5j-x2pr","CVE-2026-56359"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
