CVE-2025-14418 is a remote code execution vulnerability identified in pdfforge PDF Architect version 9.1.74.23030, classified under CWE-356 (Insufficient UI Warning). The vulnerability stems from the product's failure to warn users adequately when processing XLS files containing potentially dangerous scripts. Specifically, the software allows execution of embedded scripts within XLS files without prompting or alerting the user, which can be exploited by attackers to execute arbitrary code in the context of the current user. Exploitation requires user interaction, such as opening a malicious XLS file or visiting a crafted webpage that triggers the vulnerability. The CVSS v3.0 score is 7.0, reflecting high severity, with attack vector local (AV:L), high attack complexity (AC:H), 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). Although no known exploits are reported in the wild, the vulnerability poses a significant risk due to the potential for arbitrary code execution, which could lead to data theft, system compromise, or disruption of services. The vulnerability was reserved and published in December 2025, with no patch links currently available, indicating that remediation may be pending. The issue highlights the importance of secure handling of embedded scripts in document processing applications and the need for clear user warnings to prevent inadvertent execution of malicious code.

For European organizations, the impact of CVE-2025-14418 can be substantial, especially in sectors heavily reliant on PDF Architect for document management, such as finance, legal, government, and healthcare. Successful exploitation could lead to unauthorized access to sensitive data, disruption of business operations, and potential lateral movement within networks if attackers gain code execution capabilities. The vulnerability affects confidentiality, integrity, and availability, as attackers can execute arbitrary code to steal data, modify documents, or deploy ransomware. Since exploitation requires user interaction, phishing or social engineering campaigns could be used to deliver malicious XLS files. The lack of current patches increases exposure time, and organizations with insufficient endpoint protection or user training are at higher risk. Additionally, the vulnerability could undermine trust in document workflows and compliance with data protection regulations like GDPR if data breaches occur.

1. Monitor pdfforge's official channels for patches addressing CVE-2025-14418 and apply them promptly once released. 2. Implement strict controls on handling XLS files, including blocking or sandboxing XLS attachments from untrusted sources. 3. Employ application whitelisting to restrict execution of unauthorized scripts or code within PDF Architect and related processes. 4. Enhance email and web filtering to detect and quarantine malicious XLS files or links leading to them. 5. Conduct targeted user awareness training focusing on the risks of opening unsolicited XLS files and recognizing phishing attempts. 6. Utilize endpoint detection and response (EDR) solutions to identify suspicious behaviors indicative of exploitation attempts. 7. Consider disabling or limiting script execution features within PDF Architect if configurable. 8. Maintain regular backups and incident response plans to mitigate potential damage from exploitation. 9. Review and tighten local user privileges to minimize the impact of code execution under user context. 10. Coordinate with IT and security teams to monitor for indicators of compromise related to this vulnerability.
