Description

A use-after-free vulnerability exists in the annotation handling of Foxit PDF Reader before 2025.2.1, 14.0.1, and 13.2.1 on Windows and MacOS. When opening a PDF containing specially crafted JavaScript, a pointer to memory that has already been freed may be accessed or dereferenced, potentially allowing a remote attacker to execute arbitrary code.
