Foxit PDF: use after free

High7.8CVE-2026-57242 · Published Jul 8, 2026 · updated Jul 9, 2026

The application opens the PDF, and JavaScript modifies the form. However, the related objects on the page lack complete lifecycle management and null value validation; when the page state changes, the application continuously dereferences invalid objects, eventually leading to a crash.
