The tough library (Rust/crates.io) prior to version 0.7.1 does not properly verify the threshold of cryptographic signatures. It allows an attacker to duplicate a valid signature in order to circumvent TUF requiring a minimum threshold of unique signatures before the metadata is considered valid. A fix is available in version 0.7.1. CVE-2020-6174 is assigned to the same vulnerability in the TUF reference implementation.

 https://cve.radiocsirt.org/vuln/ghsa-5q2r-92f9-4m49 GHSA-5q2r-92f9-4m49 — Improper verification of signature threshold in tough 2026-10-05T04:48:24.573034+00:00

Affected: crates.io: tough

## Impact

The tough library, prior to 0.7.1, does not properly verify the uniqueness of keys in the signatures provided to meet the threshold of cryptographic signatures. It allows someone with access to a valid signing key to create multiple valid signatures in order to circumvent TUF requiring a minimum threshold of unique keys before the metadata is considered valid.

AWS would like to thank Erick Tryzelaar of the Google Fuchsia Team for reporting this issue.
