CVE-2026-13127: CWE-416 Use after free in Foxit Software Inc. Foxit PDF Editor
The application opens the PDF file. JavaScript then rewrites the document to modify the page structure, resulting in the invalidation of the page objects. However, the thumbnails still use the invalid page objects, ultimately causing the application to crash.
AI Analysis
Technical Summary
The vulnerability arises from the application opening a PDF file where embedded JavaScript rewrites the document to alter the page structure. This rewriting invalidates the page objects, but the thumbnail rendering process still uses these invalidated objects, leading to a use-after-free condition that causes the application to crash. The CVSS vector indicates local attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can cause the Foxit PDF Editor application to crash, potentially leading to denial of service. The CVSS score indicates high impact on confidentiality, integrity, and availability, but no known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is currently available. Users should monitor Foxit Software Inc. advisories for updates and apply patches once released.
