Brakeman 4.10.1 Released

This releases fixes Ruby 3.0 compatibility (meaning running under 3.0, new syntax is not supported yet).

Changes since 4.10.1:

  • Declare REXML as a dependency (Ruby 3.0 compatibility)
  • Use Sexp#sexp_body instead of Sexp#[..] (Ruby 3.0 compatibility)
  • Prevent render loops when template names are absolute paths (#1536)
  • Ensure RubyParser is passed file path as a String (#1534)
  • Support new Haml 5.2.0 escaping method (#1517)

REXML as an Explicit Dependency

In Ruby 3.0, REXML has become a ‘bundled’ gem. It is distributed with Ruby, but if Bundler is involved then it needs to be declared as an explicit dependency.

If you like minimal dependencies, you can always use the brakeman-min gem which declares only strict dependencies.

Avoid Slicing with Sexp#[]

Sexp subclasses from Array, and Array no longer returns subclasses from methods that create new arrays.

Brakeman was unfortunately using Sexp#[] with ranges (e.g. s(:a, :b, :c)[1..-1]), which runs into this behavior. Happily, the Sexp#sexp_body method already exists to properly slice and return a Sexp.

(changes)

Recursive Renders with Absolute Paths

Brakeman has long been able to detect recursive render loops, but that detection did not work if the partial name was an ‘absolute’ path.

This is now fixed!

(changes)

Ensure RubyParser Path is a String

In some cases, the parser was given a Brakeman::FilePath for the file name. This only caused an issue in some weird corner cases, but it was wrong nonetheless.

Now Brakeman::FileParser will ensure the file name is passed as a string.

(changes)

Support Haml 5.2

Haml 5.2.0 introduced a new method for escaping output, which caused some false positives.

(Note this was avoided in Brakeman 4.10.0 by bundling an earlier version of Haml.)
