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.","score":9.3,"severity":"critical","published":"2026-10-30T19:33:01.720Z","modified":"2026-10-30T19:33:01.720Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"akuity","name":"kargo","platforms":[],"versions":[{"version":"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"}],"cpes":[],"source":"GitHub_M","url":"https://www.cve.org/CVERecord?id=CVE-2026-61850"}],"remediation":[],"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"],"sources":[{"name":"CVE","id":"CVE-2026-61850","modified":"2026-10-30T19:33:01.720Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-61850"}],"assessments":[{"source":"GitHub_M","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","score":9.3}],"sourceAffected":[],"observedAt":"2026-10-30T20:45:50.602Z","kev":{"status":"not-listed","checkedAt":"2026-10-31T02:55:33.139Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
