weasyprint: WeasyPrint helps web developers to create PDF documents
CVE-2025-68616 is fixed in 5 products on 1 platform, first by DEBIAN-CVE-2025-68616, released January 19, 2026. It is not reported as exploited. Patch Radar priority: High.
WeasyPrint helps web developers to create PDF documents. Prior to version 68.0, a server-side request forgery (SSRF) protection bypass exists in WeasyPrint's `default_url_fetcher`. The vulnerability allows attackers to access internal network resources (such as `localhost` services or cloud metadata endpoints) even when a developer has implemented a custom `url_fetcher` to block such access. This occurs because the underlying `urllib` library follows HTTP redirects automatically without re-validating the new destination against the developer's security policy. Version 68.0 contains a patch for the issue.
