CVE-2024-25938Public exploitNetwork attack vector

Code execution via freed Barcode widget reuse

Published Apr 30, 2024 · Updated Nov 4, 2025

Use-after-free in Foxit PDF Reader 2024.1.0.23997 allows remote attackers to execute arbitrary code through a malicious PDF. A Barcode field Calculate callback can call deletePages() twice, freeing its CBF_Widget object before Foxit later uses that object without validation. Exploitation requires a user to open the document, or to visit a malicious site when the browser plugin is enabled, and can corrupt memory or run attacker-controlled code.
