Overview

Affected versions of this package are vulnerable to Use After Free in the dom_node_set_text_content function. An attacker can execute arbitrary code or cause a denial of service. The attack's success depends on a registered handler to set the parent node's text content again, and on the event dispatcher of the original call chain to resume execution.
