CVE-2026-3779: Foxit PDF Editor/Reader List Box Calculate Array Use-After-Free Vulnerability

The application's list box calculate array logic keeps stale references to page or form objects after they are deleted or re-created, which allows crafted documents to trigger a use-after-free when the calculation runs and can potentially lead to arbitrary code execution.
