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.

The version of awscli installed on the remote host is prior to 1.27.51-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2AWSCLI1-2026-001 advisory.

    (CVE-2026-13769)

    Key exchange without entity authentication in the EMR SSH helper commands in Amazon AWS CLI before 1.45.28     and AWS CLI v2 before 2.35.3 might allow man-in-the-middle attackers to intercept SSHsessions and file     transfers via network positioning between the client and the EMR cluster endpoint.



    To remediate this issue, users should upgrade to AWS CLI v1 1.45.28 or later, or AWS CLI v2 2.35.3 or     later. (CVE-2026-18654)

Tenable has extracted the preceding description block directly from the tested product security advisory.
