{"id":"CVE-2026-44791","aliases":["GHSA-wrwr-h859-xh2r"],"url":"https://o3.security/vulnerability/CVE-2026-44791","summary":"n8n: XML Node Prototype Pollution Patch Bypass","details":"## Impact\nAn authenticated user with permission to create or modify workflows could bypass the patch for GHSA-hqr4-h3xv-9m3r in the XML node. When combined with other nodes, this could lead to RCE on the n8n host.\n\n## Patches\nThe issue has been fixed in n8n versions 1.123.43, 2.20.7, and 2.22.1. 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 XML node by adding `n8n-nodes-base.xml` 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.\n\n---\nn8n has adopted CVSS 4.0 as primary score for all security advisories. CVSS 3.1 vector strings are provided for backwards compatibility.\n\nCVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","published":"2026-06-23T15:54:17.298Z","modified":"2026-08-12T03:51:28.996927305Z","cvss":null,"epss":{"score":0.00634,"percentile":0.47438,"asOf":"2026-08-15"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"n8n","fixedVersion":"1.123.43"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.22.1"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.20.7"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44791.json"},{"type":"ADVISORY","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-wrwr-h859-xh2r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44791"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-hqr4-h3xv-9m3r"},{"type":"PACKAGE","url":"https://github.com/n8n-io/n8n"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:28.996927305Z"}}
