CVE-2025-14409
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSoda PDF Desktop PDF File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Soda PDF Desktop. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PDF files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-27120.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOut-of-bounds write vulnerability in Soda PDF Desktop's PDF file parser. Due to insufficient validation of user-supplied data during PDF parsing, an attacker can write past the end of an allocated buffer, potentially achieving arbitrary code execution in the context of the current user process.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if Soda PDF Desktop is installedOn Windows, open Control Panel > Programs and Features, or use PowerShell: Get-ItemProperty 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*' | Where-Object {$_.DisplayName -like '*Soda*PDF*'} | Select-Object DisplayName, DisplayVersionAffected if Soda PDF Desktop appears in the installed programs list
-
Verify the installed version numberIf installed, note the DisplayVersion value from the previous check, or right-click the desktop shortcut and select Properties to view the version info, or check the executable: right-click the Soda PDF executable file (typically in C:\Program Files\Soda PDF\) and view Properties > DetailsAffected if The version displayed is 14.0.509.23030 exactly
-
Confirm the PDF parsing component is presentVerify the main Soda PDF application files exist in the installation directory (default: C:\Program Files\Soda PDF\) - look for the main executable and PDF-related DLLsAffected if The application is fully installed and the PDF parser component is present
If Soda PDF Desktop version 14.0.509.23030 is installed, the environment is directly affected by this vulnerability when processing malicious PDF files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUsers should avoid opening untrusted or unexpected PDF files from unverified sources until a vendor patch is available. Organizations may consider application sandboxing or isolation for PDF handling as a compensating control.
