CVE-2026-6968 (GCVE-0-2026-6968)
Vulnerability from nvd – Published: 2026-04-24 19:44 – Updated: 2026-04-24 20:10
VLAI
Title
Multiple Path Traversal Variants in awslabs/tough
Summary
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.

Title
Missing Delegated Metadata Validation in awslabs/tough
Summary
Missing expiration, hash, and length enforcement in delegated metadata validation in awslabs/tough before tough-v0.22.0 allows remote authenticated users with delegated signing authority to bypass TUF specification integrity checks for delegated targets metadata and poison the local metadata cache, because load_delegations does not apply the same validation checks as the top-level targets metadata path.
We recommend you upgrade to tough-v0.22.0 / tuftool-v0.15.0.

Title
Signature Threshold Bypass in awslabs/tough Delegated Roles
Summary
Improper verification of cryptographic signature uniqueness in delegated role validation in awslabs/tough before tough-v0.22.0 allows remote authenticated users to bypass the TUF signature threshold requirement by duplicating a valid signature, causing the client to accept forged delegated role metadata.
We recommend you upgrade to tough-v0.22.0 / tuftool-v0.15.0.

Title
Missing Delegated Metadata Validation in awslabs/tough
Summary
Missing expiration, hash, and length enforcement in delegated metadata validation in awslabs/tough before tough-v0.22.0 allows remote authenticated users with delegated signing authority to bypass TUF specification integrity checks for delegated targets metadata and poison the local metadata cache, because load_delegations does not apply the same validation checks as the top-level targets metadata path.
We recommend you upgrade to tough-v0.22.0 / tuftool-v0.15.0.

Title
Signature Threshold Bypass in awslabs/tough Delegated Roles
Summary
Improper verification of cryptographic signature uniqueness in delegated role validation in awslabs/tough before tough-v0.22.0 allows remote authenticated users to bypass the TUF signature threshold requirement by duplicating a valid signature, causing the client to accept forged delegated role metadata.
We recommend you upgrade to tough-v0.22.0 / tuftool-v0.15.0.
