CVE-2025-14408 is a security vulnerability identified in Soda PDF Desktop version 14.0.509.23030, classified as an out-of-bounds read (CWE-125) during PDF file parsing. The vulnerability occurs because the software fails to properly validate user-supplied data within PDF files, leading to reads beyond the end of allocated memory objects. This can result in the disclosure of sensitive information from the process memory. Exploitation requires user interaction, such as opening a crafted malicious PDF or visiting a malicious webpage that triggers the vulnerable PDF parsing component. Although the immediate impact is limited to information disclosure, the vulnerability can be chained with other exploits to achieve arbitrary code execution within the context of the Soda PDF process. The CVSS v3.0 score is 3.3, reflecting low severity due to the need for local access or user interaction and limited confidentiality impact. No public exploits or active exploitation have been reported to date. The vulnerability was reserved and published in December 2025 and was tracked under ZDI-CAN-27143. The lack of an available patch at the time of reporting necessitates cautious handling of PDF files and monitoring for updates from the vendor.

For European organizations, the primary impact of CVE-2025-14408 is the potential leakage of sensitive information from memory when processing malicious PDF files. This could expose confidential data, intellectual property, or personally identifiable information, depending on what resides in the process memory at the time of exploitation. While the vulnerability alone does not allow code execution, it could be leveraged in multi-stage attacks to escalate privileges or execute arbitrary code, increasing the risk profile. Organizations in sectors with heavy reliance on PDF documents—such as legal, finance, government, and healthcare—may face increased risk. The requirement for user interaction reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks. Given the low CVSS score, the immediate operational impact is limited; however, data confidentiality breaches could have regulatory and reputational consequences under GDPR and other European data protection laws.

1. Monitor Soda PDF vendor communications and apply security patches promptly once released to address CVE-2025-14408. 2. Restrict the opening of PDF files from untrusted or unknown sources, especially via email or web downloads. 3. Employ endpoint protection solutions capable of detecting anomalous behavior related to PDF parsing or memory access violations. 4. Use sandboxing or isolated environments for opening PDFs from external sources to contain potential exploitation. 5. Educate users about the risks of opening unsolicited or suspicious PDF attachments and links. 6. Implement network-level controls to block access to known malicious sites that could host exploit PDFs. 7. Conduct regular security assessments and penetration testing focused on document handling workflows. 8. Consider application whitelisting or restricting Soda PDF Desktop usage to trusted users and systems only.
