Technical Analysis
Hurl is a command line tool for running HTTP requests defined in plain text. In versions 8.0.1 and earlier, when a redirect changes the host, the redirect handling strips Authorization and Cookie headers and basic-auth credentials, but it does not strip RequestSpec.cookies created from the dedicated [Cookies] section. As a result, an attacker-controlled redirect can receive authentication or session cookies that should be scoped only to the original host. Cookies supplied via a raw Cookie header are not affected by this issue. The vulnerability is addressed in version 8.1.0.
Potential Impact
An attacker controlling a redirect can receive sensitive authentication or session cookies that should remain scoped to the original host, potentially leading to unauthorized access or session hijacking. However, cookies sent via raw Cookie headers are not affected. The vulnerability has a CVSS 4.0 score of 6.9 (medium severity).
Mitigation Recommendations
Upgrade to version 8.1.0 or later where this issue is fixed. No other mitigation is indicated by the vendor advisory.
