How to Fix CVE-2026-43003

To remediate this vulnerability, upgrade all affected Ironic python agent 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-python-agent fixed: 11.6.0 
pip install ironic-python-agent>=11.6.0
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-python-agent

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-43003, inspect your installed packages using pip:

pip show ironic-python-agent

Analyze the terminal output to locate any version of Ironic python agent in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 11.6.0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-829: Inclusion of Functionality from Untrusted Control Sphere, where the product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere. In Ironic python agent, 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

An issue was discovered in OpenStack ironic-python-agent 1.0.0 through 11.5.0. Ironic Python Agent (IPA) sometimes executes grub-install from within a chroot of the deployed partition image, leading to code execution in the case of a malicious image.
