CVE-2024-21636

Summary

CVE-2024-21636 is a cross-site scripting vulnerability that affects the view_component framework in Ruby on Rails. Versions prior to 3.9.0 and 2.83.0 are impacted if a component directly rendered from a controller with the view_component gem defines a `#call` method or uses the `#output_postamble` method. These versions have been patched to fully mitigate the vulnerabilities. As a workaround, users can sanitize the return value of the `#call` method. The vulnerability poses a medium risk and requires user interaction, potentially allowing attackers to execute malicious scripts and compromise the confidentiality and integrity of an organization's data.
