CVE-2026-3774
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 · uneditedThe application allows PDF JavaScript and document/print actions (such as WillPrint/DidPrint) to update form fields, annotations, or optional content groups (OCGs) immediately before or after redaction, encryption, or printing. These script‑driven updates are not fully covered by the existing redaction, encryption, and printing logic, which, under specific document structures and user workflows, may cause a small amount of sensitive content to remain unremoved or unencrypted as expected, or result in printed output that slightly differs from what was reviewed on screen.
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 · moderate confidenceThe application has a logic gap in its PDF processing where JavaScript embedded in document actions (WillPrint/DidPrint) can execute after redaction, encryption, or printing operations complete. This allows the script to modify form fields, annotations, or optional content groups post-operation, potentially leaving sensitive content unredacted/unencrypted or causing printed output to differ from on-screen preview.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify Foxit PDF product is installedCheck Program Files for Foxit PDF Editor or Foxit Reader installation directories, or look in Windows Registry under HKLM\SOFTWARE\Foxit Software for installed productsAffected if Foxit PDF Editor or Foxit PDF Reader is present on the system
-
Determine installed version numberOpen Foxit, go to Help > About, or check the executable file properties (right-click the Foxit exe > Properties > Details > File version)Affected if Version falls within any of these affected ranges: <= 13.2.2.24014, >= 14.0.0.33046 and <= 14.0.2.33402, >= 2023.1.0.15510 and <= 2023.3.0.23028, >= 2024.1.0.23997 and <= 2024.4.1.27687, >= 2025.1.0.27937 and <= 2025.3.0.35737 (for Reader: <= 2025.3.0.35737)
-
Confirm JavaScript execution is enabledIn Foxit, go to File > Preferences > JavaScript and verify if Enable Adobe JavaScript is checked, or inspect the application settings file for JavaScript settingsAffected if JavaScript execution is enabled in the Foxit application settings
A user is affected if they have a Foxit PDF product installed matching the affected version ranges AND JavaScript execution is enabled in the application preferences.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataDisable JavaScript execution in PDF documents or flatten/sanitize documents before performing sensitive operations to prevent post-operation script execution.
