CVE-2022-23476 Open this link in a new tabHow to fix?
Upgrade nokogiri to version 1.13.10 or higher.
Overview
nokogiri is a gem for parsing HTML, XML, SAX, and Reader.
Affected versions of this package are vulnerable to Unchecked Return Value due to failing to check the return value from xmlTextReaderExpand in the method Nokogiri::XML::Reader#attribute_hash. Exploiting this vulnerability can lead to a null pointer exception when parsing invalid markup.
Mitigation
Users may be able to search their code for calls to either XML::Reader#attributes or XML::Reader#attribute_hash to determine if they are affected.
