How to Fix CVE-2026-42997
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.
pip install ironic-python-agent>=35.0.1pip install ironic-python-agent>=32.0.1pip install ironic-python-agent>=29.0.5pip install ironic-python-agent>=26.1.6Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show ironic-python-agentHow to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2026-42997, inspect your installed packages using pip:
pip show ironic-python-agentAnalyze 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 35.0.1), 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-669: Incorrect Resource Transfer Between Spheres, where the product does not properly transfer a resource/behavior to another sphere, or improperly imports a resource/behavior from another sphere, in a manner that provides unintended control over that resource. In Ironic python agent, software state validation or input boundaries are circumvented during processing.
