Read about this release on our blog.

This is a security update (CVE-2026-55073, GHSA-r543-q48m-4c9j).

We strongly recommend to upgrade WeasyPrint to the latest version if you: * embed untrusted images, or * rely on the URL fetcher to filter metadata or stylesheets passed as Python parameters.

Security

• Don’t render EPS images.
• Always use original URL fetcher when available.
