Bug#1139189: weasyprint: CVE-2025-68616: SSRF protection bypass via HTTP redirects in default_url_fetcher

[Fox Inta - Foxi Labs]

Appreciate the quick re-triage. I see the tracker now associates CVE-2025-68616 
with src:weasyprint across all releases, so the merge request I mentioned isn't 
needed. 

Thank you,
Fox
