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:

view_component is a framework for building reusable, testable, and encapsulated view components in Ruby on Rails. Versions prior to 3.9.0 and 2.83.0 have a cross-site scripting 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` methodis not sanitized, which can also lead to cross-site scripting issues. Versions 3.9.0 and 2.83.0 have been released and fully mitigate both the `#call` and the `#output_postamble` vulnerabilities. As a workaround, sanitize the return value of `#call`.
