CVE-2025-14412 Overview
CVE-2025-14412 is a remote code execution vulnerability in Soda PDF Desktop. The flaw exists in the application's handling of XLS files. Soda PDF Desktop allows execution of dangerous script content without presenting a user warning, enabling arbitrary code execution in the context of the current user.
Exploitation requires user interaction. The target must open a malicious XLS file or visit a malicious page that delivers one. The vulnerability is tracked under Zero Day Initiative advisory ZDI-25-1085 (ZDI-CAN-27495) and is categorized as [CWE-356]: Product UI Does Not Warn User of Unsafe Actions.
Critical Impact
An attacker can execute arbitrary code with the privileges of the user running Soda PDF Desktop after the user opens a crafted XLS file.
Affected Products
- Soda PDF Desktop 14.0.509.23030
- Vendor: Sodapdf
- Component: sodapdf:soda_pdf

Technical Details for CVE-2025-14412
Vulnerability Analysis
The vulnerability resides in the XLS file handling logic of Soda PDF Desktop. When the application processes an XLS file, it permits embedded scripts or active content to execute without surfacing a security prompt to the user. This omission breaks a fundamental safety boundary that users rely on when opening documents from untrusted sources.
Because the dangerous action proceeds silently, the user has no opportunity to abort the operation. Code runs under the same privileges as the user account that opened the file. On a workstation where that account holds administrative rights, the attacker gains full control of the host.
The issue is local in attack vector, meaning the malicious file must reach the target system. Common delivery channels include email attachments, drive-by downloads, and shared file repositories.
Root Cause
The root cause is a missing user-interface security warning, classified as [CWE-356]. The application's document parser does not enforce a confirmation step before invoking embedded scripting features in XLS content. Standard mitigations such as Protected View or macro-disabled defaults, common in mainstream office suites, are absent or bypassed in the affected build.
Attack Vector
An attacker crafts an XLS file containing malicious script content. The file is delivered to a victim through phishing, a watering-hole site, or a file-sharing platform. When the victim opens the file with Soda PDF Desktop, the embedded script executes without prompt. The attacker's payload then runs with the victim's privileges, allowing actions such as dropping additional malware, harvesting credentials, or pivoting laterally.
Further technical detail is available in the Zero Day Initiative Advisory ZDI-25-1085.
Detection Methods for CVE-2025-14412
Indicators of Compromise
- Unexpected child processes spawned by SodaPDFDesktop.exe, particularly cmd.exe, powershell.exe, wscript.exe, or mshta.exe.
- XLS files arriving via email or download that are subsequently opened by Soda PDF Desktop rather than a spreadsheet application.
- Outbound network connections initiated by Soda PDF Desktop to untrusted hosts shortly after a document open event.
Detection Strategies
- Monitor process-creation telemetry for Soda PDF Desktop spawning scripting interpreters or shell processes, which is anomalous behavior for a PDF application.
- Inspect file-open events for XLS extensions associated with sodapdf processes and correlate with subsequent file write or registry modification activity.
- Use behavioral identification to flag document-handler processes that perform credential access, persistence, or lateral movement actions.
Monitoring Recommendations
- Enable command-line and parent-child process logging on endpoints running Soda PDF Desktop.
- Forward endpoint telemetry to a centralized analytics platform for correlation across users opening similar XLS files.
- Alert on Soda PDF Desktop network egress to non-corporate destinations, especially over uncommon ports.
How to Mitigate CVE-2025-14412
Immediate Actions Required
- Inventory all endpoints running Soda PDF Desktop, specifically version 14.0.509.23030 and earlier.
- Restrict the default file-handler association for XLS files so that they open in a spreadsheet application with macro protections rather than Soda PDF Desktop.
- Advise users to refrain from opening XLS attachments in Soda PDF Desktop until a vendor patch is applied.
Patch Information
No vendor advisory URL was published in the NVD entry at the time of writing. Administrators should monitor the Sodapdf vendor channel and the Zero Day Initiative Advisory ZDI-25-1085 for patch availability and apply the fixed build as soon as it is released.
Workarounds
- Block inbound XLS attachments at the email gateway when the recipient population uses Soda PDF Desktop.
- Apply application control rules that prevent SodaPDFDesktop.exe from launching scripting interpreters such as powershell.exe, cmd.exe, and wscript.exe.
- Remove or disable Soda PDF Desktop on systems where an alternative PDF reader meets business needs until the vulnerability is patched.
