Cargo can be coerced to share credentials between registries_CVE-2026-5222

{
    "lastseen": "",
    "description": "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.\u00a0The severity of the vulnerability is **low**, due to the extremely niche requirements needed to achieve the attack.",
