| Doc Text: |
A flaw was found in WeasyPrint. When processing documents with external image references, the image loading mechanism passes untrusted image data to the underlying image library without restricting unsafe formats such as Encapsulated PostScript (EPS). A remote attacker could provide a crafted document referencing malicious PostScript content to trigger Ghostscript interpretation. On systems with Ghostscript installed, this flaw can lead to arbitrary code execution.
