CVE-2026-91793

Name of the Vulnerable Software and Affected Versions Foxit PDF Editor/Reader (affected versions not specified)

Description Opening a specially crafted PDF causes the application to execute scripts that modify annotation rich-text attributes containing malformed font data. During the subsequent reconstruction of the annotation appearance, the software accesses an object after it has been released, leading to a use-after-free condition and an application crash. A use-after-free is a memory corruption issue that occurs when an application continues to use a pointer after it has been freed.
