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

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 Annotation objects. 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-22721.

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. Check if Foxit PDF software is installed
    Open Control Panel > Programs and Features, or use PowerShell: Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion | Where-Object {$_.DisplayName -like '*Foxit*'}
    Affected if Foxit PDF Reader or Foxit PDF Editor appears in the installed programs list
  2. Identify the specific Foxit product and version
    Right-click the Foxit application icon, select Properties, and view the Details tab to see the Version field. Alternatively, locate the executable (FoxitReader.exe or FoxitPDFEditor.exe) in the installation directory, right-click, and view Properties > Details
    Affected if The product is Foxit PDF Reader or Foxit PDF Editor with a version number that matches the affected ranges provided
  3. Compare installed version against affected ranges for Foxit PDF Reader
    For PDF Reader, check if version is <= 2023.3.0.63083 or <= 2023.3.0.23028. These are the vulnerable versions based on the CVE data
    Affected if The installed PDF Reader version falls within or below these version numbers, meaning it is affected
  4. Compare installed version against affected ranges for Foxit PDF Editor
    For PDF Editor, check if version matches any of these vulnerable ranges: <= 11.1.6.0109; >= 12.0.0 <= 12.1.2.55366; >= 13.0.0 <= 13.0.1.61866; >= 2023.1.0.55583 <= 2023.3.0.63083; <= 11.2.8.53842; >= 12.0.0 <= 12.1.4.15400; >= 13.0.0 <= 13.0.1.21693; >= 2023.1.0.15510 <= 2023.3.0.23028
    Affected if The installed PDF Editor version falls within any of these version ranges, meaning it is affected
  5. Determine if PDF files with annotations are processed
    The vulnerability specifically exists in Annotation object handling. Opening any PDF file that uses Foxit's annotation features (comments, highlights, notes, forms) triggers the vulnerable code path
    Affected if The user opens PDF documents containing annotation objects in the affected Foxit application

A user is affected if Foxit PDF Reader or Foxit PDF Editor is installed with a version matching any of the affected ranges and the application processes PDF files containing annotation objects.
