Why security matters in Vue - Quick Recap

Recall & Review

beginner

What is the main reason security is important in Vue applications?

Security is important in Vue apps to protect user data and prevent attacks like Cross-Site Scripting (XSS) that can harm users or steal information.

beginner

How does Vue help prevent Cross-Site Scripting (XSS) attacks by default?

Vue automatically escapes HTML in templates, so user input is shown as text, not as executable code, which helps stop XSS attacks.

Why should you avoid using v-html with untrusted content in Vue?

Using v-html with untrusted content can let attackers run harmful scripts because it inserts raw HTML without escaping, opening the door to XSS attacks.

beginner

What is a common security risk when handling user input in Vue apps?

A common risk is trusting user input without checking it, which can lead to injection attacks or broken app behavior.

intermediate

Name one best practice to improve security in Vue applications.

One best practice is to sanitize any HTML content before displaying it with v-html, ensuring no harmful code runs.

What does Vue do by default to protect against XSS attacks?

A Blocks all external scripts

B Disables JavaScript in the browser

C Escapes HTML in templates automatically

D Encrypts all user data

Vue escapes HTML in templates by default to prevent malicious scripts from running.

Why is using v-html with untrusted content risky?

A It slows down the app

B It disables Vue reactivity

C It removes all styles

D It can run harmful scripts if content is not sanitized

v-html inserts raw HTML, so untrusted content can include harmful scripts leading to XSS attacks.

Which of these is a good security practice in Vue apps?

A Trust all user input without checks

B Sanitize HTML content before rendering with v-html

C Use inline JavaScript in templates

D Disable Vue's template escaping

Sanitizing HTML content helps prevent malicious code from running when using v-html.

What kind of attack tries to run malicious scripts in your Vue app through user input?

A Cross-Site Scripting (XSS)

B SQL Injection

C Denial of Service

D Phishing

XSS attacks inject malicious scripts via user input to harm users or steal data.

Which Vue feature helps reduce security risks automatically?

A Template HTML escaping

B Reactive data binding

C Vue Router

D Vuex state management

Vue escapes HTML in templates by default, helping prevent script injection.
