Hi, The following vulnerability was published for weasyprint. CVE-2026-106443[0]: | WeasyPrint helps web developers to create PDF documents. Prior to | 70.0, the image-loading path in weasyprint/images.py passes fetched | image bytes from HTML img URLs, CSS image values, SVG image | references, and data URIs to Pillow's generic image dispatcher | without excluding EPS or PostScript formats. On hosts with | Ghostscript installed, Pillow EpsImagePlugin invokes the interpreter | for attacker-controlled PostScript, which can produce interpreter- | permitted effects and can lead to remote code execution when the | installed Ghostscript version has a usable sandbox bypass. Hosts | without Ghostscript do not reach this rasterization path. This issue | is fixed in version 70.0. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
