CVE-2026-5942 Details
Description
Flaws in page lifecycle management allow document structure changes to desynchronize internal component states, causing subsequent operations to access invalidated objects and crash the program.
A use-after-free vulnerability has been identified in multiple Foxit products, including Foxit PDF Reader and Foxit PDF Editor, all on Windows. This vulnerability arises when the application mishandles certain document elements, such as XFA files or annotation objects, allowing access to invalidated objects. Exploitation of this flaw could result in program crashes and, in some cases, unauthorized code execution.
Users can update to the latest versions of Foxit PDF Reader or Foxit PDF Editor. Instructions for updating are available on the Foxit website.
