An issue was discovered in RDoc 6.3.3 through 6.6.2, as distributed in Ruby 3.x through 3.3.0. When parsing .rdoc_options (used for configuration in RDoc) as a YAML file, object injection and resultant remote code execution are possible because there are no restrictions on the classes that can be restored. When loading the documentation cache, object injection and resultant remote code execution are also possible if there were a crafted cache.

I don't think this affects generated documents, only rubygem-rdoc is affected if possible.
This is the official announcement: https://www.ruby-lang.org/en/news/2024/03/21/rce-rdoc-cve-2024-27281/ This is the patch: https://github.com/ruby/rdoc/commit/33221979e3a6a18de962553b56c396abb5ba3244 And I'd like to elaborate that having `.rdoc_options` file around does not mean the package is vulnerable. It could be in theory, but using upstream sources, the chances are minimal.
