{"id":"AZL-88281","summary":"CVE-2026-5222 affecting package rust for versions less than 1.90.0-9","details":"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.","modified":"2026-08-30T05:26:50Z","published":"2026-05-25T10:16:15Z","upstream":["CVE-2026-5222"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-5222"}],"affected":[{"package":{"name":"rust","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/rust"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.85.0"},{"fixed":"1.90.0-9"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-88281.json"}}],"schema_version":"1.9.0"}
