Answer in brief
CVE-2026-106443 records a High severity (CVSS 8.8) vulnerability in WeasyPrint: EPS images reach the Ghostscript interpreter resulting in RCE. The current sources do not mark it as known exploited. The current feed maps Kozea/WeasyPrint (generic), WeasyPrint (pip). Check affected ranges and fixed versions before updating.

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.
