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 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-22947.

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
    Open the application and go to Help > About, or check Add/Remove Programs on Windows or Applications folder on macOS for installed Foxit software
    Affected if Foxit PDF Reader or Foxit PDF Editor is present on the system
  2. Determine the installed version number
    In the application, navigate to Help > About Foxit PDF Reader/Editor. Note the exact version string displayed (for example, 2023.3.0.63083 or 13.0.1.21693)
    Affected if The version matches any of the affected ranges provided in the CVE advisory
  3. Confirm the product type
    Verify whether the installed application is Foxit PDF Reader specifically or Foxit PDF Editor, as version ranges differ between these two products
    Affected if The product is Foxit PDF Reader with version <= 2023.3.0.63083 or <= 2023.3.0.23028, or Foxit PDF Editor with any of the multiple affected version ranges listed
  4. Verify AcroForms are being processed
    Open any PDF files that contain AcroForms (form fields) to trigger the vulnerable AcroForms handling code path. PDFs with interactive forms will exercise this functionality
    Affected if PDFs containing AcroForms are opened or processed by the vulnerable version

You are affected if Foxit PDF Reader or Foxit PDF Editor is installed with a version matching any of the CVE-listed affected ranges and AcroForm-containing PDFs are opened.
