MEDIUM 6.1EPSS 0.17%

Does this matter?

Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.

URL parameters are directly embedded into JavaScript code or HTML attributes without proper encoding or sanitization. This allows attackers to inject arbitrary scripts when an authenticated user visits a crafted link. This issue affects na1.foxitesign.foxit.com: before 2026‑01‑16.
