Background
view_component is a RubyGem that provides a framework for building reusable view components in Ruby on Rails applications. It allows developers to encapsulate UI elements into reusable components, improving code organization and reusability. However, versions 2.31.0 to 2.31.2 and versions 2.32.0 to 2.49.1 of view_component are vulnerable to a cross-site scripting (XSS) attack. This vulnerability arises when user input is not properly sanitized before being passed as an argument to the translate method, which can lead to the execution of malicious scripts on the user's browser.
Vulnerability Detail
The XSS vulnerability in view_component arises due to improper neutralization of user input during web page generation. When user input is passed as an interpolation argument to the translate method without proper sanitization, it can be rendered as HTML on the page, allowing an attacker to inject and execute arbitrary scripts. This can lead to various security risks, including session hijacking, defacement of web pages, and theft of sensitive user information. The vulnerability has a CVSS score of 8.1, indicating a high severity level.
How To Fix
Latest published version: 4.19.0 as of 23 Oct 2026
gem install view_component -v 4.19.0Upgrading to it may include breaking changes; the versions below are the minimum fixed release for this vulnerability.

Workaround
If upgrading to the fixed versions is not immediately feasible, developers can implement a workaround by manually sanitizing user input before passing it to the translate method. This can be done using HTML sanitization libraries or custom sanitization functions. Here's an example of how to sanitize user input using the sanitize method from the Rails framework:
# Sanitize user input before passing to translate
sanitized_input = sanitize(user_input)
translated_text = translate(sanitized_input)
It is important to note that workarounds may not provide the same level of security as upgrading to the fixed versions, so upgrading is still recommended.
Conclusion
The XSS vulnerability in view_component can have serious security implications for applications using affected versions. It is crucial for developers to upgrade to the fixed versions or implement proper input sanitization to mitigate the risk of XSS attacks. Following secure coding practices and staying updated with security advisories can help ensure the overall security of Ruby on Rails applications.

FAQ
view_component is a RubyGem that enables developers to build reusable view components in Ruby on Rails applications. It helps improve code organization and reusability by encapsulating UI elements into self-contained components.
Cross-site scripting (XSS) is a type of security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. It occurs when user input is not properly sanitized and rendered as HTML on the page, enabling the execution of arbitrary scripts.
The XSS vulnerability in view_component allows attackers to inject and execute arbitrary scripts on web pages. This can lead to various security risks, including session hijacking, defacement of web pages, and theft of sensitive user information.
No, only versions 2.31.0 to 2.31.2 and versions 2.32.0 to 2.49.1 of view_component are affected by this XSS vulnerability. It is recommended to upgrade to versions 2.31.2 or 2.49.1 to mitigate the issue.
Developers can mitigate the XSS vulnerability in view_component by upgrading to versions 2.31.2 or 2.49.1, which have been released to fix the issue. Additionally, they should avoid passing user input directly to the translate function and ensure proper sanitization of all inputs before using them in interpolation arguments.
