CVE-2026-3777

Severity CVSS v4.0:
Pending analysis
Type:
CWE-416 Use After Free
Publication date:
01/04/2026
Last modified:
14/04/2026

Description

The application does not properly validate the lifetime and validity of internal view cache pointers after JavaScript changes the document zoom and page state. When a script modifies the zoom property and then triggers a page change, the original view object may be destroyed while stale pointers are still kept and later dereferenced, which under crafted JavaScript and document structures can lead to a use-after-free condition and potentially allow arbitrary code execution.
