CVE-2025-14407 is a vulnerability classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) affecting Soda PDF Desktop version 14.0.509.23030. The flaw exists in the PDF file parsing component where user-supplied data is not properly validated, leading to a memory corruption condition. This memory corruption can cause information disclosure, allowing an attacker to access sensitive data from the affected system. Exploitation requires user interaction, specifically opening a crafted malicious PDF file or visiting a malicious webpage that triggers the vulnerability. Although direct code execution is not achievable solely through this vulnerability, it can be combined with other vulnerabilities to execute arbitrary code within the context of the current process. The vulnerability was identified and published by the Zero Day Initiative (ZDI) as ZDI-CAN-27141. The CVSS v3.0 base score is 3.3, reflecting low severity due to the requirement for user interaction, local attack vector, and limited confidentiality impact without integrity or availability compromise. No patches or exploits are currently publicly available, but organizations should monitor for updates. The vulnerability primarily threatens confidentiality by exposing sensitive information through memory corruption during PDF parsing.

For European organizations, the primary impact is the potential disclosure of sensitive information contained in memory during PDF parsing by Soda PDF Desktop. This could include confidential documents, credentials, or other sensitive data processed by the application. Although the vulnerability does not directly allow code execution, the possibility of chaining it with other vulnerabilities raises the risk of more severe attacks, including remote code execution. Organizations in sectors such as finance, legal, government, and healthcare that frequently handle sensitive PDF documents are at higher risk. The requirement for user interaction means that social engineering or phishing campaigns could be used to exploit this vulnerability. The low CVSS score indicates limited immediate risk, but the potential for escalation and data leakage warrants attention. The absence of known exploits reduces immediate threat but does not eliminate future risk. Disruption to business operations is unlikely, but confidentiality breaches could lead to regulatory penalties under GDPR if personal data is exposed.

1. Monitor Soda PDF Desktop vendor communications and promptly apply security patches once released for version 14.0.509.23030 or affected versions. 2. Implement strict controls on PDF file sources by restricting opening PDFs from untrusted or unknown origins, especially via email or web downloads. 3. Employ endpoint protection solutions capable of detecting and blocking malicious PDF files or suspicious memory corruption behaviors. 4. Educate users on the risks of opening unsolicited or suspicious PDF attachments and visiting untrusted websites to reduce the likelihood of user interaction exploitation. 5. Use application whitelisting and sandboxing techniques to limit the impact of potential exploitation within Soda PDF Desktop. 6. Conduct regular vulnerability assessments and penetration testing focusing on PDF handling applications to identify and remediate similar issues proactively. 7. Consider network-level protections such as email filtering and web gateway controls to block malicious payload delivery vectors.
