Prior to 1.123.55, 2.25.7, and 2.26.2, a member-level user with editor access to a shared workflow could reference credentials they do not own via specific public API endpoints. Credential ownership checks were only enforced partially leading to cross-user credential access. This issue affects instances where workflow sharing is enabled and at least one workflow has been shared with a member-level user as an Editor. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.2.","state":0,"publishedAt":"2026-06-23T15:47:25.593+00:00","modifiedAt":"2026-06-23T17:03:12.592+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:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:L","score":8.5,"severity":"HIGH"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-pmqw-72cg-wx85"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54307","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54307","identifiers":["CVE-2026-54307"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
