2.10.6rc1- Upgrade ansible to this version or later
Description
A flaw was found in the Ansible Engine prior to 2.10.6rc1, 2.9.18rc1, and 2.8.19rc1, where sensitive info is not masked by default and is not protected by the no_log feature when using the sub-option feature of the basic.py module. This flaw allows an attacker to obtain sensitive information. The highest threat from this vulnerability is to confidentiality.
Affected versions
PyPI
| Package | Vulnerable | Fixed in |
|---|---|---|
| ansible | >= 2.10.0a1, < 2.10.6rc1 |
2.10.6rc1 |
| ansible | >= 2.9.0a1, < 2.9.18rc1 |
2.9.18rc1 |
| ansible | < 2.8.19rc1 |
2.8.19rc1 |
| ansible | < 2.9.19 |
2.9.19 |
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 → 2.10.6rc1
- pip
pip install --upgrade "ansible>=2.10.6rc1"- poetry
poetry add "ansible>=2.10.6rc1"- uv
uv add "ansible>=2.10.6rc1"

Weakness
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How to prevent it
- Architecture and Design: Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
CWE-522: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How to prevent it
- Architecture and Design: Use an appropriate security mechanism to protect the credentials.
- Architecture and Design: Make appropriate use of cryptography to protect the credentials.
- Implementation: Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
