Technical description

An issue was discovered in Foxit PDF and Editor for Windows and macOS before 13.2 and 2025 before 2025.2. A crafted PDF can contain JavaScript that attaches an OnBlur action on a form field that destroys an annotation. During user right-click interaction, the program's internal focus change handling prematurely releases the annotation object, resulting in a use-after-free vulnerability that may cause memory corruption or application crashes.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
