CVE-2026-57535

EUVD-2026-39420
Content injected to PDF rendering contexts could, in many places, include HTML content including <img> tags. If the src
 attribute of these images pointed to an URL, the PDF rendering engine 
would download the image from that place and display it, thereby leaking
 information about the rendering server and possibly creating an SSRF 
vector in the local network.
