How to fix?

Upgrade Minimos:latest cargo-c to version 0.10.23-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cargo-c package and not the cargo-c package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Cargo between 1.68 and 1.96 incorrectly normalized the URLs of third-party registries using the sparse index protocol. If a hosting provider allowed multiple registries to be hosted with arbitrary names within the same domain, an attacker able to publish crates in a registry could obtain the credentials of others users of the same registry. The severity of the vulnerability is low, due to the extremely niche requirements needed to achieve the attack.
