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
A use-after-free vulnerability exists in the annotation handling of Foxit PDF Reader before 2025.2.1, 14.0.1, and 13.2.1 on Windows and MacOS. When opening a PDF containing specially crafted JavaScript, a pointer to memory that has already been freed may be accessed or dereferenced, potentially allowing a remote attacker to execute arbitrary code.

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 annotation handling allows specially crafted JavaScript embedded in a PDF to access memory pointers that have already been freed. This can lead to arbitrary code execution when the attacker-controlled PDF is opened.

MitigationUpdate Foxit PDF Reader to version 2025.2.1, 14.0.1, 13.2.1 or later to patch the use-after-free vulnerability in annotation handling.

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 Foxit PDF product installation
    Open Windows Settings > Apps & Features or use PowerShell: Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*' | Where-Object {$_.DisplayName -like '*Foxit*'} | Select-Object DisplayName, DisplayVersion
    Affected if Foxit PDF Reader or Foxit PDF Editor is installed
  2. Determine exact version number
    For desktop app, click Help > About Foxit Reader/Editor. From command line (if installed): "C:\Program Files\Foxit Software\FoxitReader\FoxitReader.exe" -version (adjust path for Editor)
    Affected if Version cannot be determined or differs from installed product
  3. Compare Reader version against affected ranges
    Compare your installed version to: <= 2025.2.1.33197 or <= 2025.2.1.69005. Note: Both Reader version constraints use <=, meaning all versions up to these are affected.
    Affected if Installed version is 2025.2.1.33197 or earlier, OR 2025.2.1.69005 or earlier (for builds with that version scheme)
  4. Compare Editor version against affected ranges
    Compare against: <= 13.2.1.23955; 14.0.0.33046 to 14.0.1.33197; 2023.1.0.15510 to 2023.3.0.23028; 2024.1.0.23997 to 2024.4.1.27687; 2025.1.0.27937 to 2025.2.1.33197; also <= 13.2.1.63315; 14.0.0.33046 to 14.0.1.69005; 2023.1.0.15510 to 2023.3.0.63083; 2024.1.0.23997 to 2024.4.1.66479; 2025.1.0.27937 to 2025.2.1.69005
    Affected if Installed version falls within any of the listed ranges
  5. Check if JavaScript is enabled in application
    Open Foxit Reader/Editor, go to File > Preferences > JavaScript. Verify if Enable JavaScript is checked (typically enabled by default)
    Affected if JavaScript is enabled - the exploit requires JavaScript execution to trigger the use-after-free in annotation handling

You are affected if Foxit PDF Reader or Editor is installed and its version matches any of the affected ranges AND JavaScript is enabled in the application settings.
