Official Description

Kargo manages and automates the promotion of software artifacts. From v1.9.0 to v1.9.2, Kargo's authorization model includes a promote verb -- a non-standard Kubernetes "dolphin verb" -- that gates the ability to advance Freight through a promotion pipeline. This verb exists to separate the ability to manage promotion-related resources from the ability to trigger promotions, enabling fine-grained access control over what is often a sensitive operation. The promote verb is correctly enforced in Kargo's legacy gRPC API. However, three endpoints in the newer REST API omit this check, relying only on standard Kubernetes RBAC for the underlying resource operations (patch on freights/status or create on promotions). This permits users who hold those standard permissions -- but who were deliberately not granted promote -- to bypass the intended authorization boundary. The affected endpoints are /v1beta1/projects/{project}/freight/{freight}/approve, /v1beta1/projects/{project}/stages/{stage}/promotions, and /v1beta1/projects/{project}/stages/{stage}/promotions/downstream. This vulnerability is fixed in v1.9.3.

Technical Analysis

CVE-2026-27111 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
