Name of the Vulnerable Software and Affected Versions Hurl versions prior to 8.1.0
Description Redirect handling in the packages/hurl/src/http/client.rs file fails to properly scope cookies. While Authorization and Cookie headers and basic-auth credentials are stripped when a redirect changes host, RequestSpec.cookies created from the dedicated [Cookies] section are incorrectly carried over into the redirected request. This allows an attacker-controlled redirect to receive authentication or session cookies intended for the original host. Cookies provided via a raw Cookie header are not affected.
Recommendations Update to version 8.1.0.
