How to Fix CVE-2026-13769

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

awscli fixed: 1.44.78

pip install awscli>=1.44.78

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 awscli

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-13769, inspect your installed packages using pip:

pip show awscli

Analyze the terminal output to locate any version of AWS CLI in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.44.78), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-732: Incorrect Permission Assignment for Critical Resource, where the product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. In AWS CLI, 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

### Summary The AWS Command Line Interface (AWS CLI) is a unified tool for managing AWS services from the command line. Certain CLI subcommands wrote credential and configuration files with world-readable permissions on Unix-like systems with a default umask, allowing other local users on the same host to read credentials. ### Impact On Unix-like systems with a default umask, the following AWS CLI subcommands wrote credential or configuration files with world-readable permissions (0644) instead of owner-only (0600): - aws codeartifact login - aws iam create-virtual-mfa-device - aws deploy register Any other local user on the same host could read these files and obtain the credentials. Impacted versions: <=1.44.77 (v1) AND <=2.34.28 (v2) ### Patches This issue has been addressed in AWS CLI v1 version 1.44.78 and AWS CLI v2 version 2.34.29. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes. If you have any questions or comments about this advisory, we ask that you contact AWS Security via our vulnerability reporting page or directly via email to [aws-security@amazon.com](mailto:aws-security@amazon.com). Please do not create a public GitHub issue.
