A use-after-free vulnerability exists in the PDF file parsing of Foxit PDF Reader before 2025.2.1, 14.0.1, and 13.2.1 on Windows. A PDF object managed by multiple parent objects could be freed while still being referenced, potentially allowing a remote attacker to execute arbitrary code.

Weakness

The 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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
