{"id":"GHSA-7w2g-9mf9-324m","summary":"Hurl: Cookies in Cookies section leak when redirecting to a different host","details":"## The Bug\n\nHurl \u003c= 8.0.1 lets you define cookies two ways in a .hurl file:\n\n1. As a raw Cookie: header in the [Header]/headers area\n2. In a dedicated [Cookies] section (parsed into RequestSpec.cookies)\n\nWhen following a redirect to a different host, Hurl correctly strips security-sensitive data (Authorization, Cookie header, and basic-auth user) to avoid leaking credentials cross-host — mirroring libcurl's default behavior. But it only stripped the cookie that came in as a header. Cookies declared in the [Cookies] section were carried over to the new host unchanged — a credential-leak bug. \n\nHurl file that leaks cookies:\n\n```hurl\nGET http://localhost:8000/follow-redirect-basic-auth?change_host=true\n[Cookies]\nfruit: lemon\nHTTP 200\n```\n\nHurl file that doesn't leak cookie:\n\n```hurl\nGET http://localhost:8000/follow-redirect-basic-auth?change_host=true\nCookie: fruit=lemon\nHTTP 200\n```\n\n## Patch\n\nWith Hurl \u003c= 8.0.1, user can use `Cookie` header instead of the dedicated `[Cookies]` section.","aliases":["CVE-2026-63481"],"modified":"2026-09-02T22:15:06.033606616Z","published":"2026-09-02T22:11:11Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-09-02T22:11:11Z","nvd_published_at":"2026-08-20T17:19:15Z","cwe_ids":["CWE-201"]},"references":[{"type":"WEB","url":"https://github.com/Orange-OpenSource/hurl/security/advisories/GHSA-7w2g-9mf9-324m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63481"},{"type":"WEB","url":"https://github.com/Orange-OpenSource/hurl/pull/5119"},{"type":"WEB","url":"https://github.com/Orange-OpenSource/hurl/commit/ed91c894c2cf11704422010554037e3ba70b446e"},{"type":"PACKAGE","url":"https://github.com/Orange-OpenSource/hurl"}],"affected":[{"package":{"name":"hurl","ecosystem":"crates.io","purl":"pkg:cargo/hurl"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"8.0.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/09/GHSA-7w2g-9mf9-324m/GHSA-7w2g-9mf9-324m.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
