The vulnerability identified as CVE-2026-57247 in Foxit PDF Editor involves a use-after-free condition (CWE-416). During document processing, the application re-enters the document structure via field processing, deletes the current page, and then continues to use field objects that were obtained before the deletion. This results in illegal memory reads and causes the application to crash. The CVSS 3.1 base score is 7.8, indicating high severity with local attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability. No patch or remediation information is provided, and no known exploits in the wild have been reported.

Successful exploitation of this vulnerability can cause the Foxit PDF Editor to crash due to illegal memory access, potentially leading to denial of service.
