CVE-2025-32451Public exploitNetwork attack vector

Code execution via uninitialized signature pointer

Published Aug 13, 2025 · Updated Nov 3, 2025

Memory corruption in Foxit Software's Foxit PDF Reader 2025.1.0.27937 allows remote attackers to execute code via a malicious PDF. JavaScript creates a CPDF_Signature object with an uninitialized field, and signature processing later dereferences that pointer without validation. Exploitation requires opening the crafted document, or visiting a malicious site with the browser plugin enabled, and can crash the reader or execute code in its process.
