Doc Text:
A flaw was found in AWS CLI. Overly permissive file permissions on Unix-like systems, where the umask has not been configured to restrict file permissions, may allow other local users on the same host to read credentials. This occurs when certain AWS CLI subcommands, such as aws codeartifact login, aws iam create-virtual-mfa-device, or aws deploy register, write credentials. This vulnerability can lead to information disclosure, potentially exposing sensitive user credentials to unauthorized local attackers.

Description OSIDB Bzimport 2026-07-01 20:03:28 UTC
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.
