{"id":"CVE-2026-54310","aliases":["GHSA-c37g-w77q-m4vp"],"url":"https://o3.security/vulnerability/CVE-2026-54310","summary":"n8n: SQL Injection in Postgres v1/TimesclaeDB Nodes","details":"## Impact\nAn authenticated user with permission to create or modify workflows could supply a crafted parameters to the TimescaleDB and/or legacy Postgres v1 node's allowing arbitrary SQL to be injected and executed against the connected database within the privileges of the configured database account.\n\n## Patches\nThe issue has been fixed in n8n versions 2.25.7, and 2.26.2. 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.","published":"2026-06-23T15:40:15.345Z","modified":"2026-10-28T02:30:25.102255080Z","cvss":null,"epss":{"score":0.00394,"percentile":0.32863,"asOf":"2026-08-23"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"n8n","fixedVersion":"2.26.2"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.25.7"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54310.json"},{"type":"ADVISORY","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-c37g-w77q-m4vp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54310"},{"type":"PACKAGE","url":"https://github.com/n8n-io/n8n"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:25.102255080Z"}}
