CVE-2026-13769

Overly permissive File Permissions in AWS CLI

State: Published
Severity: 6.8 Medium
Published: Jul 1, 2026
Updated: Jul 1, 2026
Reserved: Jun 29, 2026

Description

Overly permissive file permissions in AWS CLI before 1.44.78 (v1) and 2.34.29 (v2) on Unix-like systems where the umask has not been configured to restrict file permissions (the default on most systems) may allow other local users on the same host to read credentials written by certain CLI subcommands (aws codeartifact login, aws iam create-virtual-mfa-device, aws deploy register).

To remediate this issue, users should upgrade to AWS CLI 1.44.78 (v1) or 2.34.29 (v2) or later.
