CVE-2025-14419 is a memory corruption vulnerability classified under CWE-119, found in pdfforge PDF Architect version 9.1.74.23030. The flaw exists in the PDF file parsing component, where insufficient validation of user-supplied data leads to improper restriction of operations within memory buffer bounds. This results in a memory corruption condition that can be exploited by remote attackers to execute arbitrary code within the context of the affected process. Exploitation requires user interaction, such as opening a maliciously crafted PDF file or visiting a malicious webpage that triggers the vulnerability. The vulnerability was identified and assigned by the Zero Day Initiative (ZDI) as ZDI-CAN-27902 and published on December 23, 2025. The CVSS v3.0 base score is 7.8, indicating high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No patches were listed at the time of publication, and no known exploits in the wild have been reported. The vulnerability's root cause is a lack of proper bounds checking during PDF parsing, enabling memory corruption that can be leveraged for remote code execution. This type of vulnerability is critical because PDF Architect is widely used for document handling, and exploitation can lead to full system compromise under the user context.

For European organizations, the impact of CVE-2025-14419 is significant. The vulnerability enables remote code execution, potentially allowing attackers to gain control over affected systems, steal sensitive information, manipulate documents, or disrupt operations. Organizations in finance, legal, government, and healthcare sectors that rely heavily on PDF Architect for document processing are particularly vulnerable. The requirement for user interaction means phishing or social engineering campaigns could be effective attack vectors. Compromise could lead to data breaches, intellectual property theft, ransomware deployment, or disruption of critical services. Additionally, the high confidentiality, integrity, and availability impacts mean that exploitation could severely damage organizational trust and compliance posture, especially under GDPR regulations. The lack of an immediate patch increases exposure time, necessitating interim mitigations.

1. Immediately restrict or disable the use of pdfforge PDF Architect version 9.1.74.23030 until a security patch is released. 2. Employ application whitelisting and sandboxing to limit the execution context of PDF Architect and reduce attack surface. 3. Educate users on the risks of opening unsolicited or suspicious PDF files and visiting untrusted websites. 4. Use advanced endpoint detection and response (EDR) solutions capable of detecting memory corruption and anomalous process behavior. 5. Monitor network traffic and logs for unusual activity related to PDF Architect processes. 6. Implement strict email filtering and attachment scanning to block malicious PDFs. 7. Once available, promptly apply vendor patches or updates addressing this vulnerability. 8. Consider deploying virtualized or isolated environments for handling untrusted PDF files to contain potential exploitation. 9. Maintain regular backups and incident response plans to mitigate potential ransomware or data loss scenarios stemming from exploitation.
