CVE-2026-3776
Null pointer dereference in Foxit PDF Editor/Reader when accessing stamp annotation
CVSS Score
5.5
EPSS Score
0.0%
EPSS Percentile
3th
The application does not validate the presence of required appearance (AP) data before accessing stamp annotation resources. When a PDF contains a stamp annotation missing its AP entry, the code continues to dereference the associated object without a prior null or validity check, which allows a crafted document to trigger a null pointer dereference and crash the application, resulting in denial of service.
