Overview
cargo is a Cargo, a package manager for Rust.
Affected versions of this package are vulnerable to Use of Non-Canonical URL Paths for Authorization Decisions in the URL normalization process for third-party registries using the sparse index protocol. An attacker can access credentials belonging to other users by publishing crates in a registry hosted on a provider that allows multiple registries with arbitrary names within the same domain. This is only exploitable if the hosting provider permits multiple registries with arbitrary names on the same domain and the attacker can publish crates in such a registry.
