Overview
Affected versions of this package are vulnerable to User Impersonation due to intersection observations not being recomputed when z-index changes in PaintLayer::StyleDidChange in the Blink renderer. An attacker can perform UI spoofing by serving a crafted HTML page that uses z-index changes to alter stacking/visibility without triggering paint invalidation.
