Foxit PDF: use after free

High7.8CVE-2026-57256 · Published Jul 8, 2026 · updated Jul 9, 2026

When the application opens a PDF and executes JavaScript, it performs abnormal operations on the list box field, and this operation is repeated after the form is reset. During this process, the application failed to adequately verify the validity of the form objects and their internal dictionary pointers, resulting in accessing internal members of invalid or improperly initialized fields. This led to an illegal pointer read, ultimately causing the application to crash.
