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.","published":"2026-06-23T15:47:25.593Z","modified":"2026-08-07T11:31:28.931484068Z","cvss":null,"epss":{"score":0.00347,"percentile":0.27426,"asOf":"2026-08-10"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"n8n","fixedVersion":"1.123.55"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.26.2"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.25.7"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54307.json"},{"type":"ADVISORY","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-pmqw-72cg-wx85"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54307"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:28.931484068Z"}}
