CVE-2026-11332: ansible-core Argument Injection Vulnerability
HIGHCVE-2026-11332 is a HIGH (CVSS 7.8) argument injection vulnerability (CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')) affecting ansible-core libraries in the PyPI ecosystem. The issue involves argument injection in ansible-galaxy role install leads to arbitrary code execution. Remediation is available by upgrading affected packages to version 2.16.19rc1, 2.18.18rc1, 2.19.11rc1, 2.20.7rc1, 2.21.1rc1.

How to Fix CVE-2026-11332
To remediate this vulnerability, upgrade all affected ansible-core 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 ansible-core>=2.16.19rc1pip install ansible-core>=2.18.18rc1pip install ansible-core>=2.19.11rc1pip install ansible-core>=2.20.7rc1pip install ansible-core>=2.21.1rc1Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show ansible-coreHow to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2026-11332, inspect your installed packages using pip:
pip show ansible-coreAnalyze the terminal output to locate any version of ansible-core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.16.19rc1), your application is affected.
Note: The pip show ansible-core command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection'), where the product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. In ansible-core, 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.
