A flaw was found in curl. A logic error when processing credentials from the .netrc file while performing redirects allows the transfer of credentials from the original host to the followed-to host under certain circumstances, leaking the credentials to the followed-to host.

Statement

This issue only affects curl when a `.netrc` file is used and a redirect is performed. Additionally, the `.netrc` must match the target hostname but the followed-to host does not have a password or both login and password configured. Example of a vulnerable .netrc configuration: ~~~ machine a.com login alice password alicespassword default login bob ~~~

Common Vulnerability Scoring System (CVSS) Score Details

Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
