Published Dec 11, 2025 · Updated Dec 11, 2025

Use-after-free in Foxit PDF Reader and Editor before 13.2 and 2025.2 allows attackers to execute code through crafted PDFs. An OnBlur action destroys an annotation while internal focus-change handling retains and later accesses the released object during a right-click. Exploitation requires document JavaScript and user right-click interaction; successful memory corruption can execute code or crash the application.
