What is CVE-2026-13769?
CVE-2026-13769 is a medium-severity vulnerability in AWS CLI, published on 1 Jul 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
