How to Fix CVE-2025-44021

To remediate this vulnerability, upgrade all affected Ironic dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

ironic fixed: 24.1.3 
pip install ironic>=24.1.3
ironic fixed: 26.1.1 
pip install ironic>=26.1.1
ironic fixed: 29.0.1 
pip install ironic>=29.0.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show ironic

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-44021, inspect your installed packages using pip:

pip show ironic

Analyze the terminal output to locate any version of Ironic in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 24.1.3), your application is affected.

Note: The pip show ironic command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Ironic, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

OpenStack Ironic before 29.0.1 can write unintended files to a target node disk during image handling (if a deployment was performed via the API). A malicious project assigned as a node owner can provide a path to any local file (readable by ironic-conductor), which may then be written to the target node disk. This is difficult to exploit in practice, because a node deployed in this manner should never reach the ACTIVE state, but it still represents a danger in environments running with non-default, insecure configurations such as with automated cleaning disabled. The fixed versions are 24.1.3, 26.1.1, and 29.0.1.
