{"apiVersion":"1.0","identifier":"CVE-2026-77079","description":"n8n before 2.34.1 and 2.33.4 contains an authorization bypass in the custom project role deletion (reassignment) path. When deleting a custom project role with a reassignment target, the code validated only that the target role existed and was project-scoped, performing no project-level authorization check. A user holding only the narrow role:manageProject global scope could delete any custom project role in use on the instance and reassign its holders (including themselves) to the built-in project:admin role, gaining full administrative control of projects they had no legitimate access to.","publishedAt":"2026-08-20T12:16:39","lastModifiedAt":"2026-08-25T15:16:43","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-77079","cvssScore":7.4,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:L/VA:L/SC:H/SI:H/SA:H/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","epssProbability":0.00228,"riskScore":0.76,"affectedProduct":"n8n","affectedVersions":"<2.34.1,<2.33.4","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-77079","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-77079","en":"https://www.redsauce.net/en/cves/CVE-2026-77079","fr":"https://www.redsauce.net/fr/cves/CVE-2026-77079","pt":"https://www.redsauce.net/pt/cves/CVE-2026-77079","de":"https://www.redsauce.net/de/cves/CVE-2026-77079","sk":"https://www.redsauce.net/sk/cves/CVE-2026-77079","el":"https://www.redsauce.net/el/cves/CVE-2026-77079"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-77079"}}
