CVE-2026-57244: CWE-416 Use after free in Foxit Software Inc. Foxit PDF Editor
After JavaScript resetting the form, the synchronization process lacks re-entry protection and object lifecycle verification, resulting in the failure of the control pointer during the traversal process. After the pointer fails, it still continues to dereference, causing the application to crash.
AI Analysis
Technical Summary
This vulnerability arises when JavaScript resets a form in Foxit PDF Editor. The synchronization process that follows does not properly protect against re-entry or verify the lifecycle of objects, causing a control pointer to fail during traversal. Despite the pointer failure, the process continues to dereference the pointer, resulting in a use-after-free condition that crashes the application. The CVSS 3.1 score of 7.8 indicates high impact on confidentiality, integrity, and availability. No official remediation or patch has been disclosed at this time.
Potential Impact
Successful exploitation can cause the application to crash, leading to denial of service. The CVSS vector indicates high impact on confidentiality, integrity, and availability, but no known exploits are reported in the wild. The vulnerability requires local access with low attack complexity and no privileges, but user interaction is required.
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 handling untrusted PDF files containing JavaScript forms. No official mitigation or workaround has been provided by the vendor.
