June 22, 2023

org.cyberneko.html is an html parser written in Java. The fork of org.cyberneko.html used by Nokogiri (Rubygem) raises a java.lang.OutOfMemoryError exception when parsing ill-formed HTML markup. Users are advised to upgrade to >= 1.9.22.noko2. Note: The upstream library org.cyberneko.html is no longer maintained.
