GHSA-35jj-wx47-4w8r: weasyprint (CVE-2024-28184)

Package	Ecosystem	Affected	Fixed in
weasyprint	PyPI	>=61.0, <61.2	61.2

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

WeasyPrint versions 61.0 up to but not including 61.2 are vulnerable, allowing attachment of arbitrary files and URLs to a generated PDF even when url_fetcher is configured to block file and URL access. The source does not describe the attacker's required position, so the exact conditions are unclear; the impact is that restricted content can be embedded in the output. Upgrade to WeasyPrint 61.2 or later. As a workaround, check that source HTML does not define PDF attachments, or run WeasyPrint in a sandbox that blocks filesystem and network access.
