Low: ruby24

Issue Overview:

RDoc before version 6.3.1 used to call Kernel#open to open a local file. If a Ruby project has a file whose name starts with “|” and ends with “tags”, the command following the pipe character is executed. A malicious Ruby project could exploit it to run an arbitrary command execution against a user who attempts to run the rdoc command. (CVE-2021-31799)
