Affected versions

PyPI

Package	Vulnerable	Fixed in
ansible	`< 2.2.0.0`	`2.2.0.0`

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

ansible PyPI → `2.2.0.0`

pip

pip install --upgrade "ansible>=2.2.0.0"

poetry

poetry add "ansible>=2.2.0.0"

uv

uv add "ansible>=2.2.0.0"
