CVE-2026-57245: CWE-416 Use after free in Foxit Software Inc. Foxit PDF Editor
When the application opens a PDF, traverses and builds the annotation elements related to hyperlinks, it fails to validate the abnormal annotation relationships and field combinations. This results in the internal objects entering an invalid state. Eventually, during the destruction phase, an invalid pointer write occurred, causing the application to crash.
AI Analysis
Technical Summary
This vulnerability in Foxit PDF Editor arises during the opening and processing of PDF files containing hyperlink annotations. The software does not correctly validate abnormal annotation relationships and field combinations, which causes internal objects to become invalid. When these objects are destroyed, an invalid pointer write occurs, leading to a crash. The issue is classified as CWE-416 (Use After Free). No patch or official remediation has been confirmed or published by the vendor at this time.
Potential Impact
Successful exploitation can cause the application to crash due to invalid pointer writes triggered by malformed PDF annotations. The CVSS score indicates high impact on confidentiality, integrity, and availability, but no known exploits are reported in the wild. There is no indication of code execution or data leakage beyond the crash from the provided data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution when opening PDF files from untrusted sources to avoid triggering the vulnerability.
