@danigm Thanks! The new test is failing on Windows, can you take a peek? |

Can you please rebase as well? |
This patch adds a new test that reproduces the security issue reported here: https://seclists.org/oss-sec/2025/q2/204 Doing a request to a malicious url with a prefix like "domain.com:@" will use the "domain.com" netrc credentials in the request to other domain.

I've fixed the windows failure and rebased, so now this patch just adds a new test for netrc because the code fix was added in a different pr: #6965 |

An example of this vulnerability is available with this intentionally exploitable site, as documented here, https://www.openwall.com/lists/oss-security/2025/06/03/11 |

This patch uses the "hostname" attribute from the parsed url to get the host, instead of trying to calculate the host from netloc that can produce errors when "http://username:password@domain.com" format is used.
This should fix the security issue reported here: CVE-2024-47081: Netrc credential leak in PSF requests library
