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
This vulnerability arises when Foxit PDF Editor opens a PDF file and executes JavaScript that rewrites the document to modify the page structure. This modification invalidates the page objects, but the thumbnail rendering process continues to use these invalid page objects, leading to a use-after-free condition that causes 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.
Potential Impact
Successful exploitation results in application crashes due to use-after-free, potentially leading to denial of service and possible arbitrary code execution given the high impact on confidentiality, integrity, and availability as indicated by the CVSS score.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Users should monitor Foxit Software Inc. advisories for updates and avoid opening untrusted PDF files that may contain malicious JavaScript.
