{"id":"UBUNTU-CVE-2026-82255","details":"gitoxide versions from 0.25.4 contain an HTTP credential leak vulnerability in the curl-based transport backend where credentials are sent to attacker-controlled servers after HTTP redirects. The vulnerability occurs because credential validation checks the original URL instead of the effective URL after redirect, allowing attackers to steal authentication tokens through cross-domain redirects or HTTPS-to-HTTP downgrades.","modified":"2026-09-02T16:28:28Z","published":"2026-08-28T12:16:00Z","upstream":["CVE-2026-82255"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-82255"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-82255"},{"type":"REPORT","url":"https://github.com/GitoxideLabs/gitoxide/security/advisories/GHSA-9857-6mw7-fq2m"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/gitoxide-0.25.4-http-credential-leak-via-redirect"}],"affected":[{"package":{"name":"rust-gix-transport","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rust-gix-transport?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.41.1-1","0.41.1-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.41.1-1build1","binary_name":"librust-gix-transport-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-82255.json"}},{"package":{"name":"rust-gix-transport","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rust-gix-transport?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.44.0-1","0.48.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"librust-gix-transport-dev","binary_version":"0.48.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-82255.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
