CVE-2025-69627: n/a
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.
AI Analysis
Technical Summary
CVE-2025-69627 is a heap use-after-free vulnerability in Nitro PDF Pro for Windows 14.41.1.4 within the JavaScript method this.mailDoc(). During execution, an internal XID object is allocated and freed prematurely, but the freed pointer is still passed to UI and logging helper functions. This can cause downstream functions like wcscmp() to operate on invalid or stale pointers, resulting in access violations and non-deterministic application crashes. The vulnerability is classified under CWE-416 (Use After Free) and has a CVSS v3.1 base score of 8.4, indicating high severity with local attack vector, low attack complexity, no privileges required, no user interaction, and impacts to confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to application crashes and potentially arbitrary code execution due to use of freed memory containing attacker-controlled data. The vulnerability impacts confidentiality, integrity, and availability of the affected application. However, there are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider avoiding use of the vulnerable JavaScript method this.mailDoc() or restrict usage of untrusted PDF files containing JavaScript. Monitor vendor communications for updates on patches or official mitigations.
