Brakeman version: 4.2.1
Rails version: 5.2.0
Ruby version: 2.3.4

False Positive

Brakeman's warning us about a dynamic query we build up that uses an ActiveRecord association reflection to build a query. The code looks something like this:

assoc_reflection = reflect_on_association(:foos)
foreign_key = assoc_reflection.foreign_key

Bar.joins("INNER JOIN <complex join involving custom SQL and #{foreign_key} interpolation>")

I believe this is a false positive akin to the primary_key that Brakeman ignores, but of course any additional exceptions for false positives run the risk of missing actual vulnerabilities (for instance, when a user-defined method shares that name but generates the value using unsafe user input). It's not a big deal for us either way; we can just use ApplicationRecord.connection.quote_column_name, but I'm wondering what you think about this sort of thing more generally.
