SCA: security update for github.com/akuity/kargo (GHSA-7g9x-cp9g-92mr)

critical Tenable Self-Hosted Container Security Plugin ID 437866

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 1.7.0 to before v1.7.8, v1.8.11, and
 v1.9.3, the batch resource creation endpoints of both Kargo's legacy gRPC API and newer REST API accept
 multi-document YAML payloads. Specially crafted payloads can manifest a bug present in the logic of both
 endpoints to inject arbitrary resources (of specific types only) into the underlying namespace of an
 existing Project using the API server's own permissions when that behavior was not intended. Critically,
 an attacker may exploit this as a vector for elevating their own permissions, which can then be leveraged
 to achieve remote code execution or secret exfiltration. Exfiltrated artifact repository credentials can
 be leveraged, in turn, to execute further attacks. In some configurations of the Kargo control plane's
 underlying Kubernetes cluster, elevated permissions may additionally be leveraged to achieve remote code
 execution or secret exfiltration using kubectl. This can reduce the complexity of the attack, however,
 worst case scenarios remain entirely achievable even without this. This vulnerability is fixed in v1.7.8,
 v1.8.11, and v1.9.3. (CVE-2026-27112)
