Nokogiri Command Injection Vulnerability A command injection vulnerability in Nokogiri v1.10.3 and earlier allows commands to be executed in a subprocess via Ruby's `Kernel.open` method. Processes are vulnerable only if the undocumented method `Nokogiri::CSS::Tokenizer#load_file` is being called with unsafe user input as the filename. This vulnerability appears in code generated by the Rexical gem versions v1.0.6 and earlier. Rexical is used by Nokogiri to generate lexical scanner code for parsing CSS queries. The underlying vulnerability was addressed in Rexical v1.0.7 and Nokogiri upgraded to this version of Rexical in Nokogiri v1.10.4.

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') A command injection vulnerability in Nokogiri allows commands to be executed in a subprocess via Ruby's `Kernel.open` method.

Nokogiri Command Injection Vulnerability via Nokogiri::CSS::Tokenizer#load_file A command injection vulnerability in Nokogiri v1.10.3 and earlier allows commands to be executed in a subprocess by Ruby's `Kernel.open` method. Processes are vulnerable only if the undocumented method `Nokogiri::CSS::Tokenizer#load_file` is being passed untrusted user input. This vulnerability appears in code generated by the Rexical gem versions v1.0.6 and earlier. Rexical is used by Nokogiri to generate lexical scanner code for parsing CSS queries. The underlying vulnerability was addressed in Rexical v1.0.7 and Nokogiri upgraded to this version of Rexical in Nokogiri v1.10.4. Upgrade to Nokogiri v1.10.4, or avoid calling the undocumented method `Nokogiri::CSS::Tokenizer#load_file` with untrusted user input.
