view_component Cross-site Scripting vulnerability
Impact
What kind of vulnerability is it? Who is impacted?
This is an XSS vulnerability that has the potential to impact anyone rendering a component directly from a controller with the view_component gem. Note that only components that define a #call
method (i.e. instead of using a sidecar template) are affected. The return value of the #call
method is not sanitized and can include user-defined content.
In addition, the return value of the #output_postamble
method is not sanitized, which can also lead to XSS issues.
Patches
Has the problem been patched? What versions should users upgrade to?
Versions 3.9.0 has been released and fully mitigates both the #call
and the #output_postamble
vulnerabilities.
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?
Sanitize the return value of #call
, eg:
class MyComponent < ApplicationComponent
def call
html_escape("<div>#{user_input}</div>")
end
end
