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 · unedited
Foxit PDF Reader AcroForm Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader. 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 handling of Doc objects in AcroForms. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22745.

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 confidence

This is a use-after-free vulnerability in Foxit PDF Reader's AcroForm handling, specifically in Doc object processing. The flaw results from the lack of validating an object's existence prior to performing operations on it, allowing an attacker to free memory and then reuse it, leading to arbitrary code execution in the context of the current process.

MitigationUpdate Foxit PDF Reader to the latest version once the vendor releases a patch. Until then, avoid opening untrusted PDF files and restrict user access to malicious pages.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Foxit PDF Reader or Editor is installed
    Check for Foxit application in typical installation locations (C:\Program Files\Foxit Software\ or C:\Program Files (x86)\Foxit Software\) or look for Foxit entries in Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
    Affected if Foxit PDF Reader or Foxit PDF Editor is present on the system
  2. Locate the Foxit executable and get its version
    Right-click the Foxit executable (e.g., FoxitReader.exe or FoxitPDFEditor.exe), select Properties, and check the Details tab for Product Version. Alternatively, run: Get-Item 'C:\Program Files\Foxit Software\Foxit PDF Reader\FoxitReader.exe' | Select-Object VersionInfo
    Affected if The executable exists and returns a version number
  3. Compare installed version against affected ranges
    Match your installed version number to these affected ranges: For Foxit PDF Editor: <= 11.1.6.0109; >= 12.0.0.0601 through <= 12.1.2.55366; >= 13.0.0.61829 through <= 13.0.1.61866; >= 2023.1.0.55583 through <= 2023.3.0.63083; <= 10.1.12.37872; >= 11.0.0.49893 through <= 11.2.8.53842; >= 12.0.0.12394 through <= 12.1.4.15400; >= 13.0.0.21632 through <= 13.0.1.21693; >= 2023.1.0.15510 through <= 2023.3.0.23028. For Foxit PDF Reader: <= 2023.3.0.63083 or <= 2023.3.0.23028
    Affected if The installed version falls within any of these affected ranges
  4. Confirm AcroForm handling capability is in use
    The vulnerability triggers when processing PDFs containing AcroForm fields. Check if the installed Foxit version has PDF form functionality enabled by opening a PDF with form fields or checking Help > About for form-related modules. The vulnerability applies when opening any PDF with AcroForm content
    Affected if The user opens or processes PDF files containing AcroForm fields

You are affected if Foxit PDF Reader or Foxit PDF Editor is installed with a version matching the affected ranges and you open PDF files containing AcroForm fields.
