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-22742.

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

A Use-After-Free vulnerability in Foxit PDF Reader's AcroForm handling allows remote code execution via malicious PDF files. The flaw exists in Doc object processing where the software fails to validate object existence before performing operations, leading to use-after-free conditions that can be leveraged for arbitrary code execution in the current process context.

MitigationApply vendor patches from Foxit immediately; until patched, instruct users to avoid opening PDF files from untrusted sources and disable automatic opening of PDFs in browsers.

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 check C:\Program Files\ and C:\Program Files (x86)\ for Foxit PDF Reader or Foxit PDF Editor folders
    Affected if Foxit PDF Reader or Foxit PDF Editor is installed on the system
  2. Determine the installed Foxit version
    Right-click the Foxit executable (FoxitReader.exe or FoxitEditor.exe) in Program Files, select Properties, and note the version shown on the Details or Version tab
    Affected if Unable to determine version or version field is empty
  3. Compare Reader version against affected ranges
    If Foxit PDF Reader is installed, compare its version to: <= 2023.3.0.63083 and <= 2023.3.0.23028
    Affected if Reader version is 2023.3.0.63083 or earlier, or 2023.3.0.23028 or earlier
  4. Compare Editor version against affected ranges
    If Foxit PDF Editor is installed, compare its version to the following ranges: <= 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
    Affected if Editor version falls within any of these listed vulnerable version ranges

The system is affected if Foxit PDF Reader or Foxit PDF Editor is installed and the installed version matches any of the vulnerable version ranges listed in the CVE.
