Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HSummary
CVE-2025-69624 is a high-severity NULL Pointer Dereference (CWE-476) vulnerability in Gonitro Nitro Pdf Pro. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 35th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-69624 is a NULL pointer dereference vulnerability (CWE-476) in the JavaScript implementation of the app.alert() function within Nitro PDF Pro for Windows version 14.41.1.4. The flaw arises when app.alert() is invoked with more than one argument and the first argument evaluates to null, as in the case of app.alert(app.activeDocs, true) when app.activeDocs is null. This routes the call through a fallback path for non-string arguments, where js_ValueToString() produces an invalid string pointer from the null value. That pointer is then passed without validation to JS_GetStringChars(), resulting in dereference of an invalid address and an access violation that crashes the application upon opening a crafted PDF.
The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating it is exploitable over a network with low attack complexity, no privileges or user interaction required, and unchanged scope. Remote, unauthenticated attackers can deliver a specially crafted PDF file that triggers the NULL pointer dereference, achieving denial of service through abrupt termination of the Nitro PDF Pro application.

Vulnerability Data
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…
more
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.
