{"id":"GHSA-c37g-w77q-m4vp","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.","aliases":["CVE-2026-54310"],"modified":"2026-07-20T13:45:32.236031985Z","published":"2026-06-16T17:51:32Z","database_specific":{"cwe_ids":["CWE-89"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-06-16T17:51:32Z","nvd_published_at":"2026-06-23T16:17:01Z"},"references":[{"type":"WEB","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"}],"affected":[{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.26.0"},{"fixed":"2.26.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-c37g-w77q-m4vp/GHSA-c37g-w77q-m4vp.json"}},{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.25.7"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-c37g-w77q-m4vp/GHSA-c37g-w77q-m4vp.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"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"}]}
