Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
During the process of page opening and form formatting, a JavaScript reentrancy results in an inconsistent document status. Subsequently, with outdated page information, the application attempts to access invalid addresses, causing the application to crash.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A JavaScript reentrancy vulnerability during page opening and form formatting causes document state inconsistency. When the application attempts to access memory using outdated/stale page information, it accesses invalid addresses, causing a crash (denial of service).

MitigationImplement proper synchronization and locking mechanisms to prevent JavaScript reentrancy during page/form operations. Add document state validation checks before memory access to ensure the document status is consistent.
