Overly permissive File Permissions in AWS CLI
CVE-2026-13769 is fixed in 2 products on 2 platforms, first by AWS Command Line Interface 2.34.29, released April 10, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
