Vue is a popular JavaScript framework widely used for building single-page applications. When developing a Vue project, security issues are a key issue to pay attention to, because under some improper operations, Vue can become the target of attackers. In this article, we will introduce common security risks in Vue projects and how to prevent them.

  1. XSS attack

XSS attack refers to an attacker taking advantage of website vulnerabilities to tamper with user pages or steal information by injecting code. In Vue projects, common XSS attack methods include entering dangerous data when using {{}} syntax in Vue templates, and injecting dangerous scripts into dynamically bound properties.

Prevention methods:

a. Avoid using the {{}} syntax directly in the template, and use the v-text or v-html directive where text needs to be rendered.

b. The data input by the user needs to be filtered and escaped. You can use tool libraries such as html-entities or DOMPurify to process the data.

c. For dynamically bound properties, one-way data binding needs to be used and the bound data must be processed to avoid injecting dangerous scripts.

  1. CSRF attack

CSRF attack means that the attacker uses the user's logged-in identity to complete certain operations as the user without the user's consent. . In the Vue project, the user's browser saves login information and can automatically carry authentication information such as Token in the request. Attackers can use this information to forge requests and complete some operations.

Prevention method:

a. Use Token for identity authentication and verify whether the Token matches each request.

b. Prohibit websites from completing important operations without explicit user action.

c. Use the HTTPOnly attribute to set cookies to prevent attackers from reading cookies through JS and making forged requests.

  1. SQL injection attack

SQL injection attack means that the attacker exploits the vulnerability of the website and constructs malicious SQL statements to attack the database. In the Vue project, developers need to strictly process the data entered by the user to prevent SQL injection attacks when performing database queries.

Prevention methods:

a. Avoid using the method of assembling SQL statements to query the database, and use the ORM framework or parameterized query method to avoid injection.

b. Verify and filter all input data to avoid malicious input.

c. Use appropriate database permission controls to prevent attackers from gaining system permissions through injection operations.

  1. Unsafe file upload and download

File upload and download are commonly used functions in Vue projects. Insecure file upload and download methods can cause attackers to upload malicious files or download sensitive files, causing harm to the system.

Prevention methods:

a. Verify and filter uploaded files, and refuse to upload unsafe file types or file contents.

b. Perform permission control and legality check on uploaded files to ensure that only authorized users can access and download them.

c. Store uploaded files in a separate server, and perform security settings and monitoring on the server to prevent attackers from directly attacking the file server.

When developing a Vue project, security issues are an aspect that must be considered. This article introduces common security risks and corresponding preventive measures in Vue projects, hoping to help developers prevent security issues in projects and ensure project security.
