CVE-2026-5222 is a low-severity information-disclosure vulnerability in Cargo versions shipped with Rust 1.68 through versions before Rust 1.96. Cargo applied Git-oriented normalization that strips a .git suffix to third-party registry URLs using the sparse index protocol. On generic HTTPS hosting, sparse registry locations differing only by that suffix can be distinct resources. This normalization can cause Cargo to associate credentials for a legitimate registry with an attacker-controlled registry endpoint and disclose a victim's Cargo token.
