Description

An issue was discovered in Foxit PDF and Editor for Windows and macOS before 13.2 and 2025 before 2025.2. A crafted PDF can contain JavaScript that attaches an OnBlur action on a form field that destroys an annotation. During user right-click interaction, the program's internal focus change handling prematurely releases the annotation object, resulting in a use-after-free vulnerability that may cause memory corruption or application crashes.

• CWE-416Use After FreeThe product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
