Ensure that it is safe to bypass Vue's built-in sanitization on this specific Vue component for the href attribute

I encountered an issue with a .vue file that contains an anchor tag as shown below:

<a class="login_class" :href="loginUrl">Use Universal Login</a>

When running Sonar, it raises a warning regarding the :href attribute:

Ensure that bypassing Vue's built-in sanitization is safe in this context

What would be the best approach to resolve this concern?

Answer №1

According to the documentation for Vue (Vue 2, Vue 3), it is considered risky to use user-provided URLs without proper sanitization, as this can result in the execution of unauthorized JavaScript code on the page.

It is recommended to utilize a tool like sanitize-url (available on npm) to sanitize the loginUrl before incorporating it into the :href. However, if the link is not provided by users (for example, if loginUrl is a static URL), then you may ignore these precautions and opt for a simple inline string instead.
