## Overview

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 13.11 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an authenticated user controlling a Kubernetes agent to cause sensitive authentication tokens to be sent to an unintended server due to improper redirect validation in the Kubernetes proxy.

- `gitlab >= 19.3.0, < 19.3.5`
- `gitlab >= 19.4.0, < 19.4.2`
