CVE-2022-29181: Improper Handling of Unexpected Data Type
(updated )
Nokogiri is an open source XML and HTML library for Ruby. Nokogiri prior to version 1.13.6 does not type-check all inputs into the XML and HTML4 SAX parsers, allowing specially crafted untrusted inputs to cause illegal memory access errors (segfault) or reads from unrelated memory. Version 1.13.6 contains a patch for this issue. As a workaround, ensure the untrusted input is a String by calling #to_s or equivalent.
