CVE-2024-21636 Information

Description

view_component is a framework for building reusable testable and encapsulated view components in Ruby on Rails. Versions prior to 3.9.0 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 has been released and fully mitigates both the call and the output_postamble vulnerabilities. As a workaround sanitize the return value of call.
