Rails Denial of Service vulnerability
Unspecified vulnerability in the "dependency resolution mechanism" in Ruby on Rails 1.1.0 through 1.1.5 allows remote attackers to execute arbitrary Ruby code via a URL that is not properly handled in the routing code, which leads to a denial of service (application hang) or "data loss," a different vulnerability than CVE-2006-4111.

Improper Input Validation
Ruby on Rails 2.3.9 and 3.0.0 does not properly handle nested attributes, which allows remote attackers to modify arbitrary records by changing the names of parameters for form inputs.

Cross-Site Request Forgery (CSRF)
Ruby on Rails 2.1.x, 2.2.x, and 2.3.x before 2.3.11, and 3.x before 3.0.4, does not properly validate HTTP requests that contain an X-Requested-With header, which makes it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks via forged (1) AJAX or (2) API requests that leverage "combinations of browser plugins and HTTP redirects," a related issue to CVE-2011-0696.

Translate helper method which may allow an attacker to insert arbitrary code into a page
The helper method for i18n translations has a convention whereby translations strings with a name ending in 'html' are considered HTML safe. There is also a mechanism for interpolation. It has been discovered that these 'html' strings allow arbitrary values to be contained in the interpolated input, and these values are not escaped.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
The cross-site scripting (XSS) prevention feature in Ruby on Rails 2.x before 2.3.12, 3.0.x before 3.0.8, and 3.1.x before 3.1.0.rc2 does not properly handle mutation of safe buffers, which makes it easier for remote attackers to conduct XSS attacks via crafted strings to an application that uses a problematic string method, as demonstrated by the sub method.

Denial of Service Vulnerability in Action View
There is a denial of service vulnerability in the header handling component of Action View. Strings sent in specially crafted headers will be cached indefinitely. This can cause the cache to grow infinitely, which will eventually consume all memory on the target machine, causing a denial of service.

Ruby on Rails vulnerable to code injection
Ruby on Rails before 1.1.5 allows remote attackers to execute Ruby code with "severe" or "serious" impact via a File Upload request with an HTTP header that modifies the LOAD_PATH variable, a different vulnerability than CVE-2006-4112.

Moderate severity vulnerability that affects rails
Cross-site scripting (XSS) vulnerability in the strip_tags function in Ruby on Rails before 2.2.s, and 2.3.x before 2.3.5, allows remote attackers to inject arbitrary web script or HTML via vectors involving non-printing ASCII characters, related to HTML::Tokenizer and actionpack/lib/action_controller/vendor/html-scanner/html/node.rb.

ReDoS based DoS vulnerability in Action Dispatch
There is a possible regular expression based DoS vulnerability in Action Dispatch. Specially crafted cookies, in combination with a specially crafted `X_FORWARDED_HOST` header can cause the regular expression engine to enter a state of catastrophic backtracking. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability All users running an affected release should either upgrade or use one of the workarounds immediately.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Multiple cross-site scripting (XSS) vulnerabilities in actionview/lib/action_view/helpers/number_helper.rb in Ruby on Rails beta2 allow remote attackers to inject arbitrary web script or HTML via the (1) format, (2) negative_format, or (3) units parameter to the (a) number_to_currency, (b) number_to_percentage, or (c) number_to_human helper.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Multiple cross-site scripting (XSS) vulnerabilities in the mail_to helper in Ruby on Rails before 2.3.11, and 3.x before 3.0.4, when javascript encoding is used, allow remote attackers to inject arbitrary web script or HTML via a crafted (1) name or (2) email value.
