CVE-2025-69627Public exploit

Application crash via freed XID pointer reuse

Published Apr 13, 2026 · Updated Apr 13, 2026

Heap use-after-free in Nitro PDF Pro for Windows 14.41.1.4 allows context-dependent attackers to crash the application via a crafted PDF. During this.mailDoc() handling, an XID object is freed prematurely and its dangling pointer is passed to CDumpContext::operator<< and later UI or string routines. Opening a PDF containing an argument-free this.mailDoc() call reaches the flaw; observed outcomes are access violations and nondeterministic crashes.
