Possible unprotected redirect
Open

      redirect_to @node.path
Severity: Critical
Found in app/controllers/wiki_controller.rb by brakeman

Unvalidated redirects and forwards are #10 on the OWASP Top Ten.

Redirects which rely on user-supplied values can be used to "spoof" websites or hide malicious links in otherwise harmless-looking URLs. They can also allow access to restricted areas of a site if the destination is not validated.

Brakeman will raise warnings whenever redirect_to appears to be used with a user-supplied value that may allow them to change the :host option.

For example,

redirect_to params.merge(:action => :home)

will create a warning like

Possible unprotected redirect near line 46: redirect_to(params)

This is because params could contain :host => 'evilsite.com' which would redirect away from your site and to a malicious site.

If the first argument to redirect_to is a hash, then adding :only_path => true will limit the redirect to the current host. Another option is to specify the host explicitly.

redirect_to params.merge(:only_path => true)

redirect_to params.merge(:host => 'myhost.com')

If the first argument is a string, then it is possible to parse the string and extract the path:

redirect_to URI.parse(some_url).path

If the URL does not contain a protocol (e.g., http://), then you will probably get unexpected results, as redirect_to will prepend the current host name and a protocol.

Cognitive Complexity

Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

A method's cognitive complexity is based on a few simple rules:

  • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
  • Code is considered more complex for each "break in the linear flow of the code"
  • Code is considered more complex when "flow breaking structures are nested"

Duplicated Code

Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:

Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

Tuning

This issue has a mass of 58.

We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.

The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.
