Upgrade golang.org/x/net/html to version 0.45.0 or higher.
Overview
golang.org/x/net/html is a package that implements an HTML5-compliant tokenizer and parser.
Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via the html.Parse function due to quadratic parsing complexity when processing certain inputs, which can lead to denial of service (DoS) if an attacker provides specially crafted HTML content.
