What is CVE-2026-27111?

Kargo, a tool for managing software artifacts, has a critical authorization loophole in versions 1.9.0 to 1.9.2. While its legacy gRPC API enforces strict access controls regarding software promotions, the newer REST API fails to impose the same checks on three specific endpoints. This vulnerability allows users with standard permissions to circumvent intended boundaries, potentially compromising sensitive operations in the promotion pipeline. This issue has been addressed in version 1.9.3.

Affected Version(s)

kargo >= 1.9.0, < 1.9.3
