CVE-2026-6968 · Severity: medium · CVSS 5.9 · Published 2026-04-24

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.

Technologies: [Amazon Tough](https://junglewise.ai/threats/technologies/amazon-tough), [Amazon Tuftool](https://junglewise.ai/threats/technologies/amazon-tuftool). Vendors: [Amazon](https://junglewise.ai/threats/vendors/amazon).
