Mass assignment is not restricted using attr_accessible Open

This warning comes up if a model does not limit what attributes can be set through mass assignment.
In particular, this check looks for attr_accessible
inside model definitions. If it is not found, this warning will be issued.
Brakeman also warns on use of attr_protected
- especially since it was found to be vulnerable to bypass. Warnings for mass assignment on models using attr_protected
will be reported, but at a lower confidence level.
Note that disabling mass assignment globally will suppress these warnings.

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 68.
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.
