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-22633.

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 installed Foxit product
    Check if Foxit PDF Reader or Foxit PDF Editor is installed. On Windows, look in Program Files for Foxit Software folder, or check registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for entries starting with Foxit.
    Affected if No Foxit product is found (not affected)
  2. Determine installed Foxit version
    Open Foxit Reader/Editor, go to Help > About, or right-click the application in taskbar and select Properties to view the version number. Alternatively, check the Uninstall registry entry for the DisplayVersion value.
    Affected if Unable to determine version (unknown)
  3. Compare version against affected ranges
    Compare your installed version number to these ranges: Reader: <= 2023.3.0.63083 or <= 2023.3.0.23028; Editor: <= 11.1.6.0109; >= 12.0.0.0601, <= 12.1.2.55366; >= 13.0.0.61829, <= 13.0.1.61866; >= 2023.1.0.55583, <= 2023.3.0.63083; <= 10.1.12.37872; >= 11.0.0.49893, <= 11.2.8.53842; >= 12.0.0.12394, <= 12.1.4.15400; >= 13.0.0.21632, <= 13.0.1.21693; >= 2023.1.0.15510, <= 2023.3.0.23028
