An authenticated user with read-only access to a shared workflow can use the Public API to retry executions of that workflow, bypassing the intended permission boundary between read and execute access. This affects instances where workflows are shared with other users or across projects.","state":0,"publishedAt":"2026-07-08T14:17:17.683+00:00","modifiedAt":"2026-10-25T20:10:00.147+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · disclosure@vulncheck.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":5.3,"severity":"MEDIUM"},{"system":"CVSS 3.1 · disclosure@vulncheck.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4,"severity":"MEDIUM"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-h3jj-5f3v-3685","https://www.vulncheck.com/advisories/n8n-authorization-bypass-in-public-api-execution-retry-endpoint"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-56778","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-863"],"productCriteria":["cpe:2.3:a:n8n:n8n:*:*:*:*:*:node.js:*:*"],"sourceDates":{"published":"2026-07-08T14:17:17.683","lastModified":"2026-10-25T20:10:00.147"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
