CVE-2026-13769 is a medium-severity flaw (CVSS 5.5) affecting aws command line interface. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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

amazon aws command line interface UPGRADE

Affected: < 1.44.78 · >= 2.0.0 and < 2.34.29

Fixed in: 1.44.78, 2.34.29

Safe to downgrade to: a release before 2.0.0

1. Check installed version

apt-cache policy aws-command-line-interface || rpm -q aws-command-line-interface || aws-command-line-interface --version

2. UPGRADE to 1.44.78 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade aws-command-line-interface

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade aws-command-line-interface

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.0.0 (Debian / Ubuntu)

apt-cache madison aws-command-line-interface sudo apt install aws-command-line-interface=<VERSION_BEFORE_2.0.0> sudo apt-mark hold aws-command-line-interface

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list aws-command-line-interface sudo dnf downgrade aws-command-line-interface-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add aws-command-line-interface

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
