CVE-2026-3777

The application does not properly validate the lifetime and validity of internal view cache pointers after JavaScript changes the document zoom and page state.

Published Apr 1, 2026 · updated Jun 17, 2026 · foxit pdf editor

The application does not properly validate the lifetime and validity of internal view cache pointers after JavaScript changes the document zoom and page state. When a script modifies the zoom property and then triggers a page change, the original view object may be destroyed while stale pointers are still kept and later dereferenced, which under crafted JavaScript and document structures can lead to a use-after-free condition and potentially allow arbitrary code execution.
