{"id":"DEBIAN-CVE-2025-68616","details":"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.","modified":"2026-09-01T20:05:57.496417862Z","published":"2026-01-19T16:15:53.573Z","upstream":["CVE-2025-68616"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-68616"}],"affected":[{"package":{"name":"weasyprint","ecosystem":"Debian:12","purl":"pkg:deb/debian/weasyprint?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["57.2-1","59.0-1","60.2-1","61.0-1","61.1-1","61.2-1","61.2-2","62.0-1","62.1-1","62.2-1","62.3-1","67.0-1","69.0-1","69.0-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-68616.json"}},{"package":{"name":"weasyprint","ecosystem":"Debian:13","purl":"pkg:deb/debian/weasyprint?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["62.3-1","67.0-1","69.0-1","69.0-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-68616.json"}},{"package":{"name":"weasyprint","ecosystem":"Debian:14","purl":"pkg:deb/debian/weasyprint?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"69.0-1"}]}],"versions":["62.3-1","67.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-68616.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
