CVE-2026-13129

HIGH 7.8 ALL-YEARS

Published 2026-07-08 · Last modified 2026-07-08 · Foxit · NVD: Analyzed

When the application opens a PDF file, JavaScript uses the damaged field tree to trigger field traversal, resulting in the program holding an invalid form object when accessing the field property path. Eventually, the application crashes due to reading an invalid pointer.
