An authenticated member with edit access to a shared workflow can reference another user's credential while specifying the credential type via an expression. Because the pre-execution permission check compares the unresolved expression instead of the resolved credential type, the ownership check is skipped and the credential is loaded at execution time, allowing the member to use or exfiltrate a credential they were not granted. Exploitation requires knowing the target credential's identifier.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:N","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-639"],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-6qc9-mqvw-jg7x","https://www.vulncheck.com/advisories/n8n-before-authentication-bypass-via-http-request-node"],"products":["n8n:n8n"],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-72774","score":0.00438,"percentile":0.37752,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-6qc9-mqvw-jg7x","url":"https://osv.dev/vulnerability/GHSA-6qc9-mqvw-jg7x","summary":"n8n: Credential Authorization Bypass via Expression in HTTP Request Node `genericAuthType`","modified":"2026-08-12T04:26:13.397610937Z","packages":[{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":["<1.123.67"],"fixed":["1.123.67"]},{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":[">=2.32.0 <2.32.1"],"fixed":["2.32.1"]},{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":[">=2.0.0-rc.0 <2.31.5"],"fixed":["2.31.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
