Attacker controls the redirect server requiring no privileges; victim must actively run the script (UI:R); only session cookie confidentiality is impacted with no integrity or availability loss.

Lifecycle Timeline
2DescriptionCVE.org
Hurl is a command line tool that runs and tests HTTP requests defined in plain text files. In version 8.0.1 and earlier, the redirect handling in packages/hurl/src/http/client.rs strips Authorization and Cookie headers and basic-auth credentials when a redirect changes host, but it carries RequestSpec.cookies created from the dedicated [Cookies] section into the redirected request. An attacker-controlled redirect can therefore receive authentication or session cookies that should remain scoped to the original host. Cookies supplied through a raw Cookie header are stripped and are not affected by this specific path. This issue is reported as fixed in version 8.1.0.
AnalysisAI
Cross-host redirect cookie leakage in Hurl ≤ 8.0.1 exposes session credentials to attacker-controlled redirect destinations when scripts use the dedicated [Cookies] section. Hurl's HTTP client correctly strips raw Cookie headers and Authorization credentials on host changes, but the separate RequestSpec.cookies pathway - populated by the [Cookies] section of .hurl files - bypasses this stripping logic, forwarding scoped cookies to the redirected host. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires all of the following: (1) the .hurl script must define cookies via the [Cookies] section - cookies sent via raw Cookie: headers are stripped on host change and are NOT affected by this vulnerability; (2) the script must have redirect-following enabled (--location or equivalent Hurl option); (3) a redirect must occur that changes the destination hostname, pointing to an attacker-controlled or attacker-influenced host; and (4) the script must be actively executed by a user or automated runner (CVSS UI:A). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N) assigns high confidentiality impact with low complexity, but mandates active user interaction (UI:A), meaning a developer or CI runner must execute the vulnerable script against a server that issues a cross-host redirect. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Hurl 8.1.0, which corrects the cookie-stripping logic on cross-host redirects as implemented in commit ed91c894c2cf11704422010554037e3ba70b446e (https://github.com/Orange-OpenSource/hurl/commit/ed91c894c2cf11704422010554037e3ba70b446e) via PR #5119 (https://github.com/Orange-OpenSource/hurl/pull/5119). … Detailed patch versions, workarounds, and compensating controls in full report. |
