What is CVE-2025-55309?

A use-after-free vulnerability has been identified in Foxit PDF and Foxit Editor for both Windows and macOS platforms, specifically in versions prior to 13.2 and 2025 before 2025.2. This vulnerability arises when a crafted PDF file includes JavaScript that triggers an OnBlur action associated with a form field, leading to the destruction of an annotation. An improper handling of focus changes during user interactions can result in the premature release of the annotation object, ultimately causing memory corruption or potentially crashing the application. This security risk is vital for users to acknowledge, ensuring they take appropriate measures to mitigate exposure.
