Dependency Hierarchy: - responders-3.0.0.gem (Root Library) - actionpack-6.0.0.gem - :x: **rails-html-sanitizer-1.3.0.gem** (Vulnerable Library)

Found in base branch: master
rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Certain configurations of rails-html-sanitizer < 1.4.4 use an inefficient regular expression that is susceptible to excessive backtracking when attempting to sanitize certain SVG attributes. This may lead to a denial of service through CPU resource consumption. This issue has been patched in version 1.4.4.
