{"id":"GHSA-jpq7-226w-6cxx","summary":"n8n: NoSQL Injection in MongoDB Node Find And Replace Operation","details":"## Impact\nAn authenticated user with workflow edit access could supply a malicious filter value in the MongoDB node's Find And Replace operation. The value was not validated before being passed to MongoDB as a query filter, allowing unintended documents to be matched and overwritten with attacker-controlled content.\n\n## Patches\nThe issue has been fixed in n8n version 2.24.0. Users should upgrade to this version 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 MongoDB node by adding `n8n-nodes-base.mongoDb` 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-2026-54313"],"modified":"2026-07-20T13:45:32.238266895Z","published":"2026-06-16T18:59:23Z","database_specific":{"nvd_published_at":"2026-06-23T16:17:02Z","cwe_ids":["CWE-89"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-06-16T18:59:23Z"},"references":[{"type":"WEB","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-jpq7-226w-6cxx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54313"},{"type":"PACKAGE","url":"https://github.com/n8n-io/n8n"}],"affected":[{"package":{"name":"n8n","ecosystem":"npm","purl":"pkg:npm/n8n"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.24.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-jpq7-226w-6cxx/GHSA-jpq7-226w-6cxx.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:N/I:H/A:N"},{"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"}]}
