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 workflow creation and editing permissions to fully trusted users only.\n- Disable the Postgres and TimescaleDB node by adding `n8n-nodes-base.postgres`,  `n8n-nodes-base.timescaleDb` to the `NODES_EXCLUDE` environment variable.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","state":0,"publishedAt":"2026-06-16T17:51:32+00:00","modifiedAt":"2026-07-20T13:45:32.236032+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.26.0"},{"kind":"fixed","version":"2.26.2"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.25.7"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-c37g-w77q-m4vp","https://nvd.nist.gov/vuln/detail/CVE-2026-54310","https://github.com/n8n-io/n8n"],"sourceUrl":"https://github.com/advisories/GHSA-c37g-w77q-m4vp","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-c37g-w77q-m4vp","identifiers":["GHSA-c37g-w77q-m4vp","CVE-2026-54310"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
