CVE-2026-57535
Published:June 25, 2026
Updated:June 29, 2026
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.
