How to fix?

Upgrade Debian:11 epiphany-browser to version 3.38.2-1+deb11u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream epiphany-browser package and not the epiphany-browser package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

XSS can occur in GNOME Web (aka Epiphany) before 40.4 and 41.x before 41.1 because a server's suggested_filename is used as the pdf_name value in PDF.js.
