CVE-2025-69624
Nitro PDF Pro before 14.43 for Windows contains a NULL pointer dereference vulnerability in the JavaScript implementation of app.alert(). When app.alert() is called with more than one argument and the first argument evaluates to null (for example, app.alert(app.activeDocs, true) when app.activeDocs is null), the engine routes the call through a fallback path intended for non-string arguments. In this path, js_ValueToString() is invoked on the null value and returns an invalid string pointer, which is then passed to JS_GetStringChars() without validation. Dereferencing this pointer leads to an access violation and application crash when opening a crafted PDF. For example, 14.41.1.4 and 14.42.0.34 have been reported as vulnerable.
CVE-2025-69627
Nitro PDF Pro for Windows 14.41.1.4 contains a heap use-after-free vulnerability in the implementation of the JavaScript method this.mailDoc(). During execution, an internal XID object is allocated and then freed prematurely, after which the freed pointer is still passed into UI and logging helper functions. Because the freed memory region may contain unpredictable heap data or remnants of attacker-controlled JavaScript strings, downstream routines such as wcscmp() may process invalid or stale pointers. This can result in access violations and non-deterministic crashes.

Null Pointer Dereference in Nitro PDF Pro Leads to DoS via XFA Packet
CVE-2025-67825
An issue was discovered in Nitro PDF Pro for Windows before 14.42.0.34. In certain cases, it displays signer information from a non-verified PDF field rather than from the verified certificate subject. This could allow a document to present inconsistent signer details. The display logic was updated to ensure signer information consistently reflects the verified certificate identity.
CVE-2024-35288
Nitro PDF Pro before 13.70.8.82 and 14.x before 14.26.1.0 allows Local Privilege Escalation in the MSI Installer because custom actions occur unsafely in repair mode. CertUtil is run in a conhost.exe window, and there is a mechanism allowing CTRL+o to launch cmd.exe as NT AUTHORITY\SYSTEM.
