CVE-2025-69627: n/a
Nitro PDF Pro for Windows version 14. 41. 1. 4 contains a heap use-after-free vulnerability in the JavaScript method this. mailDoc(). This flaw occurs because an internal XID object is freed prematurely but its pointer is still used in UI and logging functions, potentially leading to access violations and application crashes. The vulnerability has a high severity score of 8. 4 and can result in confidentiality, integrity, and availability impacts. No patch or official remediation guidance is currently available, and no known exploits are reported in the wild.
AI Analysis
Technical Summary
CVE-2025-69627 is a heap use-after-free vulnerability in Nitro PDF Pro for Windows 14.41.1.4 affecting 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, leading to access violations and non-deterministic 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 cause application crashes and potentially allow an attacker to execute arbitrary code or leak sensitive information due to use of freed memory containing attacker-controlled data. The CVSS score of 8.4 reflects high impact on confidentiality, integrity, and availability. However, no known exploits are currently reported in the wild.
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 limiting exposure to untrusted PDF files that may trigger the vulnerable JavaScript method. Monitor vendor communications for updates on patches or mitigations.
