## Overview

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 19.2 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 unauthenticated user to execute arbitrary code on the GitLab server via a specially crafted regular expression in a CI/CD configuration, due to insufficient regular expression validation.

## Affected

- `gitlab >= 19.2.0, < 19.2.8`
- `gitlab >= 19.3.0, < 19.3.5`
- `gitlab >= 19.4.0, < 19.4.2`

## Remediation

Upgrade past the affected range:

- `gitlab 19.4.2`
