SCA: security update for github.com/clastix/capsule-proxy, github.com/projectcapsule/capsule-proxy (GHSA-fpvw-6m5v-hqfp)

critical Tenable Cloud Security Plugin ID 414627

Description

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

 - capsule-proxy is a reverse proxy for the capsule operator project. Affected versions are subject to a
 privilege escalation vulnerability which is based on a missing check if the user is authenticated based on
 the `TokenReview` result. All the clusters running with the `anonymous-auth` Kubernetes API Server setting
 disable (set to `false`) are affected since it would be possible to bypass the token review mechanism,
 interacting with the upper Kubernetes API Server. This privilege escalation cannot be exploited if you're
 relying only on client certificates (SSL/TLS). This vulnerability has been addressed in version 0.4.6.
 Users are advised to upgrade. (CVE-2023-48312)
