Prior to 1.123.55, 2.25.7, and 2.26.2, an authenticated user with workflow edit access could configure a Respond to Webhook node to serve binary content with an attacker-controlled Content-Type. The binary response path bypassed the central Content-Security-Policy sandbox header, allowing a public webhook to execute JavaScript in the n8n origin when visited by an authenticated user, with access to that user's session. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.2.","state":0,"publishedAt":"2026-06-23T15:44:58.322+00:00","modifiedAt":"2026-06-24T14:00:17.206+00:00","affected":[{"ecosystem":"Vendor product","name":"n8n","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n8n-io\",\n                    \"product\": \"n8n\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.123.55\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.0.0-rc.0, < 2.25.7\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.26.0, < 2.26.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","score":7,"severity":"HIGH"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-v733-mwr6-fgcm"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54301","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54301","identifiers":["CVE-2026-54301"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
