SCA: security update for github.com/akuity/kargo (GHSA-5vvm-67pj-72g4)

medium Tenable Cloud Security Plugin ID 437871

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
