## Overview

A template injection flaw was found in Ansible where a user's controller internal templating operations may remove the unsafe designation from template data. This issue could allow an attacker to use a specially crafted file to introduce templating injection when supplying templating data.

## Affected packages

- `ansible-core >= 2.16.0, < 2.16.1`
- `ansible-core >= 2.15.0, < 2.15.8`
- `ansible-core < 2.14.12`

## Remediation

Upgrade to a patched release:

- `ansible-core 2.16.1`
- `ansible-core 2.15.8`
- `ansible-core 2.14.12`
