| Package | Affected versions | Patched versions |
|---|---|---|
| tough | ≥ 0.9.0, < 0.22.0 | 0.22.0 |
| tuftool | < 0.15.0 | 0.15.0 |
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.
