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 PRC File Parsing Out-Of-Bounds Read 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 parsing of PRC files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26784.

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.

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. Confirm Foxit PDF Reader installation
    Check for Foxit PDF Reader in program directories (C:\Program Files\Foxit or C:\Program Files (x86)\Foxit), Start Menu, or desktop shortcuts. Also check Windows Programs and Features list.
    Affected if Foxit PDF Reader is installed on the system
  2. Identify installed Foxit PDF Reader version
    Right-click the Foxit PDF Reader executable (e.g., FoxitReader.exe) → Properties → Details tab → Product Version. Or launch the application → Help → About Foxit Reader.
    Affected if Version is lower than 2025.1.0.27937, or version is 2025.1.0.66692 or lower (specific to the 13.x legacy versioning branch)
  3. Verify PRC file handling capability
    Check if the application can open .PRC files by attempting to open a PRC file or verifying .PRC file association in Windows Default Apps settings.
    Affected if PRC file type is associated with Foxit PDF Reader and functional

User is affected if Foxit PDF Reader is installed with a version that falls within the affected ranges AND the application is capable of opening or parsing PRC files.
