CVE-2026-57240: CWE-416 Use after free in Foxit Software Inc. Foxit PDF Editor
When the application opens a PDF file and JavaScript deletes the PDF fields, the subsequent logic still uses the old field pointers, resulting in invalid pointer references and causing the application to crash.
AI Analysis
Technical Summary
This vulnerability in Foxit PDF Editor arises from improper handling of PDF fields deleted by JavaScript. After deletion, the application logic still references the freed memory pointers, leading to use-after-free conditions. This can cause the application to crash and potentially allows an attacker to execute arbitrary code or cause denial of service. The CVSS vector indicates local attack vector with low 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, resulting in denial of service. Given the use-after-free nature and high impact scores on confidentiality, integrity, and availability, there is a potential risk of arbitrary code execution, although no exploits are currently known in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been published by Foxit Software Inc. at this time.
