12.0.1- Upgrade nova to this version or later
Description
The volume_utils._parse_volume_info function in OpenStack Compute (Nova) before 2015.1.3 (kilo) and 12.0.x before 12.0.1 (liberty) includes the connection_info dictionary in the StorageError message when using the Xen backend, which might allow attackers to obtain sensitive password information by reading log files or other unspecified vectors.
Affected versions
PyPI
| Package | Vulnerable | Fixed in |
|---|---|---|
| nova | >= 12.0.0, < 12.0.1 |
12.0.1 |
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.
nova PyPI → 12.0.1
- pip
pip install --upgrade "nova>=12.0.1"- poetry
poetry add "nova>=12.0.1"- uv
uv add "nova>=12.0.1"

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.
