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 from improper validation of annotation relationships and field combinations when opening PDFs containing hyperlinks. The flawed validation causes internal objects to become invalid, and during the destruction phase, an invalid pointer write occurs, leading to a crash. The issue is classified as CWE-416 (Use After Free). No patch or remediation information is currently available from the vendor, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation can cause the application to crash, resulting in denial of service. The CVSS vector indicates high impact on confidentiality, integrity, and availability, but exploitation requires local access and user interaction.
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 opening untrusted PDF files, especially those containing complex hyperlink annotations.
