CVE-2026-3776: CWE-476 NULL pointer dereference in Foxit Software Inc. Foxit PDF Editor
CVE-2026-3776 is a medium severity vulnerability in Foxit PDF Editor affecting versions 2025. 3 and earlier, 14. 0. 2 and earlier, and 13. 2. 2 and earlier. The flaw arises because the application does not verify the presence of required appearance (AP) data before accessing stamp annotation resources in a PDF. If a crafted PDF contains a stamp annotation missing its AP entry, the application dereferences a null pointer, causing a crash and resulting in denial of service. There is no indication of data confidentiality or integrity impact. No patch or official fix information is currently provided.
AI Analysis
Technical Summary
This vulnerability (CWE-476: NULL pointer dereference) occurs in Foxit PDF Editor when the software processes PDF files containing stamp annotations that lack the required appearance (AP) data. The application fails to check for the presence or validity of the AP entry before dereferencing the associated object. This leads to a null pointer dereference, causing the application to crash and resulting in a denial of service condition. The issue affects multiple versions of Foxit PDF Editor up to 2025.3, 14.0.2, and 13.2.2. The CVSS v3.1 base score is 5.5, reflecting a medium severity with local attack vector, low complexity, no privileges required, user interaction required, unchanged scope, and impact limited to availability.
Potential Impact
Successful exploitation causes a denial of service by crashing the Foxit PDF Editor application when opening a maliciously crafted PDF with a stamp annotation missing its AP entry. There is no impact on confidentiality or integrity. The attack requires local access and user interaction to open the malicious file.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should avoid opening untrusted PDF files containing stamp annotations. Monitor Foxit Software Inc. advisories for updates regarding patches or mitigations.
