CVE-2026-5939
A crafted XFA PDF can trigger a use-after-free condition during calculate event processing, causing the application to crash and resulting in an arbitrary code execution.
Does this matter?
Lower severity and a low EPSS score (0.11%). Track it; it rarely justifies an emergency change on its own.
