CVE-2026-6968

Multiple Path Traversal Variants in awslabs/tough

Published: Apr 24, 2026Updated: May 6, 2026 Sources: CVE List NVDCWE-22

5.9MEDIUM

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.
