CVE-2025-14419 is a remote code execution vulnerability identified in pdfforge PDF Architect version 9.1.74.23030. The root cause is an improper restriction of operations within the bounds of a memory buffer (CWE-119) during the parsing of PDF files. Specifically, the software fails to properly validate user-supplied data embedded in PDF documents, which leads to memory corruption. This corruption can be exploited by an attacker who crafts a malicious PDF file or hosts a malicious webpage containing such a file. When a user opens the malicious PDF or visits the webpage, the vulnerability triggers, allowing the attacker to execute arbitrary code within the context of the current process. The CVSS v3.0 score of 7.8 reflects high severity, with attack vector local (requiring user interaction), low attack complexity, no privileges required, and impacts on confidentiality, integrity, and availability. Although no public exploits are known at this time, the vulnerability poses a significant risk due to the widespread use of PDF Architect in document management workflows. The lack of available patches at the time of disclosure necessitates immediate mitigation efforts to reduce exposure. The vulnerability was reported by the Zero Day Initiative (ZDI) as ZDI-CAN-27902 and was published on December 23, 2025.

For European organizations, this vulnerability threatens the confidentiality, integrity, and availability of systems running pdfforge PDF Architect. Successful exploitation could lead to full system compromise, data theft, or disruption of business operations. Sectors heavily reliant on PDF Architect for document processing, such as legal, financial, healthcare, and government agencies, are particularly vulnerable. The requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious PDFs. Given the high CVSS score and the critical nature of document workflows, exploitation could result in significant operational and reputational damage. Additionally, the vulnerability could be leveraged as an initial foothold for lateral movement within networks. The absence of known exploits currently provides a window for proactive defense, but the risk of rapid weaponization remains.

Organizations should immediately audit their environments to identify installations of pdfforge PDF Architect version 9.1.74.23030 and earlier. Until patches are released, restrict the use of PDF Architect to trusted users and environments. Employ application whitelisting to prevent execution of unauthorized PDF files. Enhance email and web filtering to block or quarantine suspicious PDF attachments and links. Educate users about the risks of opening unsolicited or unexpected PDF files, especially from unknown sources. Deploy endpoint detection and response (EDR) solutions capable of detecting anomalous memory corruption or code execution behaviors. Monitor network traffic for unusual activity originating from hosts running PDF Architect. Coordinate with pdfforge for timely patch deployment once available. Consider sandboxing PDF Architect or opening PDFs in isolated environments to limit potential damage.
