NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

When processing an HTTP redirect to a URL containing userinfo (a username:password component), curl might erroneously retain and re-transmit the original host's HTTP Negotiate authentication state. Consequently, a malicious server can trigger a redirect containing arbitrary userinfo to force curl to send a freshly minted Kerberos ticket—generated using the ambient identity of the client process to an untrusted third-party host, effectively bypassing the domain-scoping restrictions normally enforced by the absence of --location-trusted.
