Pointer Dereference Flaw in JavaScript Form Reset

Publication date: 2026-07-08

Last updated on: 2026-07-09

Assigner: Foxit

Description

After JavaScript resetting the form, the synchronization process lacks re-entry protection and object lifecycle verification, resulting in the failure of the control pointer during the traversal process. After the pointer fails, it still continues to dereference, causing the application to crash.

Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This vulnerability occurs after JavaScript resets a form, where the synchronization process does not have proper re-entry protection or verification of the object's lifecycle. As a result, the control pointer fails during traversal but continues to be dereferenced, which causes the application to crash.

Impact Analysis

The impact of this vulnerability is that it can cause the affected application to crash. This can lead to denial of service, potentially disrupting normal operations and affecting availability.
