Possible DoS Vulnerability
A carefully crafted email address in conjunction with the Action Mailer logger format string could take advantage of a bug in Ruby's sprintf implementation and possibly lead to a denial of service attack. Impacted Ruby code will look something like this: `"some string #{user_input}" % some_number`

Arbitrary file existence disclosure
Specially crafted requests can be used to determine whether a file exists on the filesystem that is outside an application's root directory. The files will not be served, but attackers can determine whether the file exists.

Log Plaintext Password Local Disclosure
REST Client for Ruby contains a flaw that is due to the application logging password information in plaintext. This may allow a local attacker to gain access to password information.

Reflective XSS Vulnerability
When a translation is missing, the HTML exception message raised does not escape the keys. Under certain common configurations this string can contain user input which would allow an attacker to execute a reflective XSS attack.

Session fixation vulnerability via Set-Cookie headers
The package rest-client in `abstract_response.rb` improperly handles `Set-Cookie` headers on HTTP redirection responses. Any cookies will be forwarded to the redirection target regardless of domain, path, or expiration. If you control a redirection source, you can cause rest-client to perform a request to any third-party domain with cookies of your choosing, which may be useful in performing a session fixation attack. If you control a redirection target, you can steal any cookies set by the third-party redirection request.
