CVE-2026-13769

Local credential disclosure via world-readable file creation

Published Jul 1, 2026 · Updated Jul 1, 2026

Incorrect file permissions in AWS CLI before 1.44.78 and 2.34.29 allow local users to read credentials from files created by three subcommands. The codeartifact login, iam create-virtual-mfa-device, and deploy register paths create credential or configuration files with mode 0644 rather than owner-only mode 0600. Exploitation requires another local account on the same Unix-like host and a nonrestrictive umask, which is the default on most systems.
