AI-suggested

AWS recommends upgrading to tough version 0.22.0 or tuftool version 0.15.0, which contain fixes for this path traversal vulnerability. Since this is a cloud service component, AWS manages remediation for the cloud-hosted service. Users should verify they are using the patched versions and consult the AWS security bulletin at https://aws.amazon.com/security/security-bulletins/2026-019-aws/ for the latest guidance.

Description

Incomplete path traversal fixes in awslabs/tough before tough-v0.22.0 allow remote authenticated users with delegated signing authority to write files outside intended output directories via absolute target names in copy_target/link_target, symlinked parent directories in save_target, or symlinked metadata filenames in SignedRole::write, because write paths trust the joined destination path without post-resolution containment verification. We recommend you upgrade to tough-v0.22.0 / tuftool-v0.15.0.
