CVE-2025-55314 vulnerability security high severity Foxit PDF memory corruption arbitrary code execution CVE database

Summary

CVE-2025-55314 is a high-severity vulnerability affecting Foxit PDF Editor and Reader. This vulnerability stems from improper memory management when deleting pages via JavaScript, potentially leading to memory corruption and arbitrary code execution.

Technical Details

CVE-2025-55314 arises from a flaw in how Foxit PDF Editor and Reader handle internal states after pages are deleted using JavaScript. Specifically, when a page is deleted through JavaScript, the application fails to properly update its internal data structures. Subsequent operations related to annotation management then operate on these outdated and invalid states. This leads to the dereferencing of memory that has either been released or is otherwise invalid. This dereferencing can trigger memory corruption, causing the application to crash. In a more severe scenario, an attacker could leverage this memory corruption to inject and execute arbitrary code within the context of the application.

The vulnerability is triggered when a PDF document containing JavaScript code that deletes pages is opened in a vulnerable version of Foxit PDF Editor or Reader. The JavaScript code manipulates the document structure, leading to the inconsistent state. The subsequent annotation management operations then trigger the memory corruption.

Affected Products and Versions

The following Foxit products and versions are affected by CVE-2025-55314:

  • Foxit PDF Editor versions prior to 13.2 on Windows and macOS
  • Foxit PDF Editor versions prior to 2025.2 on Windows and macOS
  • Foxit PDF Reader versions prior to 13.2 on Windows and macOS
  • Foxit PDF Reader versions prior to 2025.2 on Windows and macOS

Impact Assessment

Successful exploitation of CVE-2025-55314 can have significant consequences:

  • Application Crash: The most immediate impact is application instability, leading to crashes and disruption of user workflows.
