{"id":"CVE-2026-61850","state":"PUBLISHED","title":"Kargo: Privilege escalation via Project RBAC management in the Kargo API","description":"Kargo manages and automates the promotion of software artifacts. From 0.6.0 until 1.8.14, 1.9.9, and 1.10.8, two authorization flaws in the `project-scoped RBAC API` let an authenticated user with delegated permission to manage a Project's `Roles` or `ServiceAccounts` confer permissions exceeding the user's own. A user authorized to edit `Roles` can create, replace, or add rules granting permissions not held by the user; a user authorized to edit a Role's ServiceAccount can bind an identity, including the user's own, to a more powerful Role. A Kargo Role comprises a `ServiceAccount, Role, and RoleBinding` in the Project namespace. Changes are written using the API server's broadly privileged credentials after only a coarse resource-kind edit check, rather than checking each permission being conferred. This permits escalation to Project-administrator access, disclosure of `Project Secrets` and credentials, and modification or deletion of Project resources. Stolen Git, container-registry, or Helm-registry credentials can extend confidentiality and integrity impacts to those external systems. Escalation remains limited to Projects where the attacker already has RBAC-management delegation and does not itself grant cluster-wide or cross-Project access. Default non-administrator roles do not permit these operations; exploitation requires an `administrator-created custom role` granting the relevant permissions and control of an account assigned that role. This issue is fixed in versions 1.8.14, 1.9.9, and 1.10.8.","publishedAt":"2026-10-30T19:33:01.720Z","updatedAt":"2026-10-30T19:33:01.720Z","severity":{"score":9.3,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["akuity kargo"],"affected":[{"vendor":"akuity","product":"kargo","versions":[{"version":">= 0.6.0, < 1.8.14","status":"affected"},{"version":">= 1.9.0-rc.1, < 1.9.9","status":"affected"},{"version":">= 1.10.0-rc.1, < 1.10.8","status":"affected"}]}],"references":["https://github.com/akuity/kargo/security/advisories/GHSA-wp4p-hr79-q4g8","https://github.com/akuity/kargo/commit/19639678811b486bddb014dabb25397771f3941e","https://github.com/akuity/kargo/commit/50d29c10153965114f903645c83eadbe7bf58d3f","https://github.com/akuity/kargo/commit/5ab7c4216a4151f55ea8ef9ff3b9f884dd322578","https://github.com/akuity/kargo/commit/72fadd3600b35e6dce67042eb686720a48b45fa3","https://github.com/akuity/kargo/releases/tag/v1.10.8","https://github.com/akuity/kargo/releases/tag/v1.11.0-rc.1","https://github.com/akuity/kargo/releases/tag/v1.8.14","https://github.com/akuity/kargo/releases/tag/v1.9.9"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-30T19:48:04.455Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/61xxx/CVE-2026-61850.json","commit":"91beacf46587178cb335e3399e6db92524d41de0","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-61850","state":"PUBLISHED","datePublished":"2026-10-30T19:33:01.720Z","dateUpdated":"2026-10-30T19:33:01.720Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-07-10T20:28:17.513Z"},"containers":{"cna":{"title":"Kargo: Privilege escalation via Project RBAC management in the Kargo API","descriptions":[{"lang":"en","value":"Kargo manages and automates the promotion of software artifacts.
