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.","cvss_v4":{"vector":"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","score":7.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","score":6.8},"cwes":["CWE-522"],"references":["https://github.com/GitoxideLabs/gitoxide/security/advisories/GHSA-9857-6mw7-fq2m","https://www.vulncheck.com/advisories/gitoxide-0.25.4-http-credential-leak-via-redirect"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-82255","score":0.00384,"percentile":0.32182,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-9857-6mw7-fq2m","url":"https://osv.dev/vulnerability/GHSA-9857-6mw7-fq2m","summary":"gix-transport: HTTP credentials leaked to redirected host in curl backend","modified":"2026-10-01T03:56:08.037992750Z","packages":[{"ecosystem":"crates.io","name":"gix-transport","purl":"pkg:cargo/gix-transport","ranges":[">=0.25.4 <0.56.0"],"fixed":["0.56.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
