Rest-client Project

REST client for Ruby (aka rest-client) before 1.8.0 allows remote attackers to conduct session fixation attacks or obtain sensitive cookie information by leveraging passage of cookies set in a response to a redirect.

The rest-client gem 1.6.10 through 1.6.13 for Ruby, as distributed on RubyGems.org, included a code-execution backdoor inserted by a third party.

REST client for Ruby (aka rest-client) before 1.7.3 logs usernames and passwords, which allows local users to obtain sensitive information by reading the log.
