Prior to 2.25.7 and 2.26.2, a prototype pollution vulnerability allowed a crafted public webhook payload to inject attacker-controlled fields into workflow data during internal object copying. These fields could be surfaced and consumed as normal values by downstream built-in nodes. Where a workflow combines a public webhook with action nodes that consume the resulting fields, an attacker could cause the workflow to act as a confused deputy — targeting unintended records or issuing outbound requests using the workflow owner's configured credentials. This vulnerability is fixed in 2.25.7 and 2.26.2.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","score":6.3,"severity":null}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-2vff-hj5x-8gq7"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-38474","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Jun 23, 2026, 3:43:12 PM","dateUpdated":"Jun 26, 2026, 7:29:51 PM"},"relatedAdvisories":[{"id":"NCSC-2026-0212","title":"Kwetsbaarheden verholpen in n8n workflow automation platform","vulnerabilityIds":["CVE-2026-54301","CVE-2026-54302","CVE-2026-54304","CVE-2026-54305","CVE-2026-54306","CVE-2026-54307","CVE-2026-54308","CVE-2026-54309","CVE-2026-54310","CVE-2026-54311","CVE-2026-54312","CVE-2026-54313","CVE-2026-54314","CVE-2026-54303"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
