Tagging a string as html safe may be a security risk. Open
link_to(t.html_safe, metamorphosize_if(object))
- Read upRead up
- Exclude checks
This cop checks for the use of output safety calls like html_safe
,
raw
, and safe_concat
. These methods do not escape content. They
simply return a SafeBuffer containing the content as is. Instead,
use safe_join
to join content and escape it and concat to
concatenate content and escape it, ensuring its safety.
Example:
user_content = "hi"
# bad
"#{user_content}
".html_safe
# => ActiveSupport::SafeBuffer "hi
"
# good
content_tag(:p, user_content)
# => ActiveSupport::SafeBuffer "<b>hi</b>
"
# bad
out = ""
out << "#{user_content} "
out << "#{user_content} "
out.html_safe
# => ActiveSupport::SafeBuffer "hi
hi "
# good
out = []
out << content_tag(:li, user_content)
out << content_tag(:li, user_content)
safe_join(out)
# => ActiveSupport::SafeBuffer
# "<b>hi</b>
<b>hi</b> "
# bad
out = "trusted content
".html_safe
out.safe_concat(user_content)
# => ActiveSupport::SafeBuffer "trusted_content
hi"
# good
out = "trusted content
".html_safe
out.concat(user_content)
# => ActiveSupport::SafeBuffer
# "trusted_content
<b>hi</b>"
# safe, though maybe not good style
out = "trusted content"
result = out.concat(user_content)
# => String "trusted contenthi"
# because when rendered in ERB the String will be escaped:
# <%= result %>
# => trusted content<b>hi</b>
# bad
(user_content + " " + content_tag(:span, user_content)).html_safe
# => ActiveSupport::SafeBuffer "hi <span><b>hi</b></span>"
# good
safe_join([user_content, " ", content_tag(:span, user_content)])
# => ActiveSupport::SafeBuffer
# "<b>hi</b> <span><b>hi</b></span>"

This cop identifies possible cases where Active Record save! or related should be used instead of save because the model might have failed to save and an exception is better than unhandled failure.
This will allow:
- update or save calls, assigned to a variable,
or used as a condition in an if/unless/case statement.
- create calls, assigned to a variable that then has a
call to persisted?
.
- calls if the result is explicitly returned from methods and blocks,
or provided as arguments.
- calls whose signature doesn't look like an ActiveRecord
persistence method.
By default it will also allow implicit returns from methods and blocks.
that behavior can be turned off with AllowImplicitReturn: false
.
You can permit receivers that are giving false positives with
AllowedReceivers: []

# bad
