CVE-2026-13129: CWE-416 Use after free in Foxit Software Inc. Foxit PDF Editor
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.
AI Analysis
Technical Summary
This vulnerability involves a use-after-free condition (CWE-416) in Foxit PDF Editor. When the application processes a PDF file with JavaScript that triggers field traversal on a damaged field tree, it retains an invalid form object. Accessing the field property path then leads to dereferencing an invalid pointer, causing the application to crash. The CVSS 3.1 vector indicates the attack requires local access with low complexity, no privileges, and user interaction, impacting confidentiality, integrity, and availability at a high level. No official remediation or patch information is available at this time.
Potential Impact
Successful exploitation results in a program crash due to reading an invalid pointer, leading to denial of service. The CVSS score and vector indicate potential high impact on confidentiality, integrity, and availability, but no known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution when opening PDF files from untrusted sources and consider disabling JavaScript execution within the application if possible.
