According to lớn the US National Vulnerability Database (NVD), in 2020,103 security vulnerabilities were disclosed. This is the highest number of security vulnerabilities ever recorded & almost quadruples the number of vulnerabilities in the past decade. From these,70% provided malicious actors with an attack vector.

This is a scary prospect for any company looking khổng lồ build or maintain its digital presence as it leaves you vulnerable to lớn all kinds of cyberattacks. While having a CMS gives you an extra layer of security, not every CMS is created equal. Traditional —or coupled CMS— lượt thích WordPress or Drupal are often even more vulnerable to lớn attacks. In this article, we discuss the đứng top CMS security vulnerabilities và how enlisting a headless CMS can mitigate them.

What Is a Security Vulnerability, Anyway?


The NVD defines a vulnerability as “a weakness in the computational xúc tích và ngắn gọn (e.g., code) found in software and hardware components that, when exploited, results in a negative impact khổng lồ confidentiality, integrity, or availability.”

In the context of a CMS, a vulnerability occurs when a malicious actor targets a CMS platform for something other than its intended purpose. The tin tặc exploits that access khổng lồ compromise the CMS’ underlying infrastructure to gain access to lớn the servers or initiate attacks against other tenants.

How a Headless CMS prevents the top 6 Security Vulnerabilities?

The collaborative nature of CMSs increases the number of potential attack surfaces. If you địa chỉ cửa hàng multiple users with different notions of cybersecurity to the mix, the number of potential vulnerabilities can sharply increase. Let’s take a look at the most common CMS security vulnerabilities.

SQL Injection

SQL injections are among the most common attacks on CMSs. SQL injection is similar to other injection attacks because it introduces arbitrary SQL code into the database layer, enabling attackers to issue direct database commands and manipulate the database as if it were the CMS user. Due to lớn the new security measures CMSs —especially headless CMS— have implemented & the relatively easy methods khổng lồ foil these attacks, they are less effective every day. Headless CMSs can mitigate these attacks to the databases by enabling you lớn use non-SQL databases to lớn store và distribute your nội dung or give you different CDN options if you want to lớn use SQL.

Brute-force Attacks

Brute-force attacks can be carried out by almost everyone since they involve entering multiple login credentials over a period of time until the right one is discovered. Some CMSs don’t limit the number of login attempts by default which means that users leveraging those CMSs are exposed khổng lồ malicious actors who can enter hundreds or thousands of credentials until they find one that works. Even if a brute force attack fails, it can still wreak havoc on your server as too many attempts will overload & slow your system down. A headless CMS uses sign-in & authentication protocols & monitors logins with automated tools to lớn identify login abnormalities and mitigate brute-force attacks.


Distributed denial-of-service is an enhanced version of the denial-of-service attack where a malicious actor sends a large volume of requests to lớn a server with the purpose of making it crash or inaccessible lớn its intended users. DDoS attacks are often executed via many different machines —also known as botnets— which hide the origin of the requests. Modern headless CMSs render the nội dung on the client side using APIs and reduce the load on the server each time a visitor accesses the website, reducing the impact of potential DDoS attacks.

Arbitrary Remote Code Execution

While arbitrary code injection requires more resources than other kinds of cyberattacks, injecting code into a website or tiện ích can have nefarious consequences to lớn the users’ privacy & data. Arbitrary remote code execution makes use of any attack surface và sends a piece of PHP code lớn the remote execution environment which, without proper security will run as if it were from the user, opening remote backdoors for attackers to lớn gain access khổng lồ the target environment. This type of attack can compromise nonSQL databases, but headless CMS can prevent this type of attack by tightening the security rules in the hosting environment.

Cross-Site Scripting (XSS)

This type of CMS vulnerability exploits the client environment within the browser which allows an attacker lớn inject arbitrary code onto the target’s instance & environment. This attack occurs on the client side, which means that it can compromise sensitive user data và allow for manipulation of the databases & stored variables. Traditional CMS platforms lượt thích Drupal and WordPress are particularly vulnerable lớn XSS vulnerabilities due to their heavier use of client-side environments. Headless CMSs that leverage server-side rendering mitigate potential XSS attacks. Server-side rendering protects the databases, so that if they manage khổng lồ gain access to the client server, the rest of the information that wasn"t queried should be safe.

File Inclusion Exploitation

File inclusion vulnerabilities are often found in poorly coded sites. This kind of vulnerability occurs when a site allows users to đầu vào or upload files to the server & the PHP code does not validate the input resulting in malicious files being delivered lớn the server. In file inclusion exploits, users can gain access khổng lồ sensitive data when the servers are misconfigured or the user has high privileges. A headless CMS can mitigate this vulnerability by restricting permission lớn upload files to the website and keep a whitelist of allowable file types khổng lồ prevent malicious files from entering into the server.


Best Practices Against CMS Vulnerabilities

When choosing a CMS, choose one where the vendors handle maintenance và updates, that way you will mitigate the risks of not updating.Perform regular database backups.Sanitize and restrict user input to prevent injection attacks.Use strong passwords và store them as encrypted valuesAlways use SSL certificates on your web server.Rename admin directories something other than ‘admin’Keep track of the latest vulnerabilities of your CMS.Leverage two-factor authentication for an additional layer of security.Scan your trang web using penetration testing tools.
