Magento Security Patch:
Your Store's Essential Digital Immune System

In the fast-paced realm of eCommerce, Magento powers countless successful online stores. Yet, like any sophisticated platform, it demands constant protection. Magento vulnerabilities are not abstract concepts; they represent tangible threats capable of eroding customer trust and business stability overnight. The only reliable shield against these evolving dangers is the timely application of Magento security patch. This isn’t merely an update; it’s a critical layer of Magento store protection.

A Magento Security Patch is a targeted, code-level fix released by Adobe (or the Magento Open Source maintainers) specifically to remediate one or more identified security vulnerabilities within the Magento Open Source or Adobe Commerce platform core code, bundled extensions, or underlying frameworks. It is not a feature update or a full version upgrade.

Its sole purpose is to address critical security flaws that could be exploited by attackers to compromise store data, functionality, or administrative access. Security bugs can leave your store vulnerable to cyber threats, and security patches provide essential security fixes to address these issues. Patches are distributed as discrete code files designed to modify specific parts of the existing Magento installation to close the security gap(s). Magento releases security patches as targeted software updates to fix bugs and vulnerabilities discovered after a Magento version is launched.

Security patches are published in two ways: through the Adobe Commerce Help Center or via Git commit. Official patches are published by Adobe on the Commerce Help Center, while custom patches may be created via Git commits.

Before you start, make sure of these prerequisites:

1. Backup. Create full backups of your Magento database and file system (including the root directory).
2. Staging Environment. Always test patch installation and functionality in a staging environment identical to production before touching your live store.
3. Identify Patch. Determine the exact patch(es) you need based on your Magento version and the vulnerabilities reported (Check the Security Center).
4. Access. SSH access to your Magento server with appropriate permissions (e.g., the Magento file system owner user).
5. FTP Access/Client. Ensure you have FTP access or an FTP client if SSH is unavailable, as these are needed to transfer patch files to the application's root directory.

Download the correct patch file(s) (.sh, .composer.json, .diff) from the official Adobe Commerce Help Center or via Composer for Magento 2.3.3+. Transfer the patch file(s) securely to your Magento root directory on the server.

Now you can apply the patch.

Using the Shell Script (.sh):

• Navigate to your Magento root directory:

chmod u+x bin/magento or sudo chmod -R 0777 bin/magento

• Make the script executable: chmod +x security_patch_name.sh
• Execute the script: ./security_patch_name.sh
• Follow any on-screen prompts. The script modifies core files.

Using Composer (Recommended for Magento 2.3.3+):

1. Add the patch package to your composer.json (details provided with the patch).
2. Run: composer require magento/security-package-name
3. Run: composer update

Find the extra section in composer.json and make sure the "extra composer exit on patch failure" setting is set to true for patches that fail. Add the patch version under patches using the above format.

1. Check the output of the installation script or Composer command for errors.
2. Run: bin/magento --version. The patch identifier (e.g., -pX) should now appear appended to your Magento version number.
3. (Optional) Use tools like diff or specialized modules to verify file changes if needed.

Don’t forget to clear caches. Run: bin/magento cache:clean and bin/magento cache:flush.

Test all critical storefront and admin functionalities in your staging environment.

Using GitHub:
!! Before you start using GitHub, consider some important details.

First of all, patches on GitHub represent source code, not ready-to-install packages. The official channel is the Magento Security Center. This method requires a deep understanding of Linux systems, command line, and Git. You may face a high probability of errors during manual merging, especially with custom modules. So use it only if the patch is unavailable via Composer or .sh installer.

• Navigate to Magento root:

cd /path/to/magento_root

• Create full backup:

Locate patch on GitHub by visiting repository.
Identify patch using:

• CVE ID (e.g., CVE-2022-24086)
• Patch ID (e.g., MDVA-12345)
• Version tag (e.g., 2.4.5-p1)

Copy the SHA hash of the fix commit.

Now you can apply patch via Git.

• Add official repo as remote (if not present):

Resolve conflicts (if any), Git will flag conflicted files. Manually resolve:

• Identify conflicted files: git status
• Edit files (remove conflict markers <<<<<<<, =======, >>>>>>>):

nano path/to/conflicting/file.php

• Mark resolved: git add path/to/conflicting/file.php

Complete process:

Then verify and deploy changes. Review patch modifications by git diff HEAD^ HEAD. Don’t forget to clear catches:

Before initiating any update process, verify the patch's relevance to your specific Magento installation:

Cross-reference the CVE identifiers mentioned in the patch notes with your current Magento version and enabled extensions. Contact third-party module vendors to confirm compatibility statements, paying special attention to extensions overriding core files or modifying checkout flows. Validate the patch aligns with your PHP version, server stack, and customizations through Adobe's official documentation.

Coordinate a maintenance window during predictable low-traffic periods, typically outside business hours for your primary market. Notify customers in advance through store banners or email communications about potential temporary unavailability. Activate Magento's maintenance mode using the command:

You can also use the enable maintenance mode command to ensure a controlled environment. Additionally, consider enabling rate limiting for 2FA OTP to prevent brute-force attacks during the update process.

Simultaneously enhance security by temporarily restricting admin panel access to trusted IP addresses and ensuring two-factor authentication is enforced for all administrative accounts.

Implement continuous security monitoring through specialized Magento scanners like MageReport (free) for instant configuration gap detection and compromised file checks. For enterprise-grade scanning, deploy Sansec eComscan which performs deep filesystem forensics and database integrity validation. Incorporate general web application scanners such as OWASP ZAP or Acunetix to identify cross-site scripting (XSS) and SQL injection vectors before patch deployment. Schedule weekly automated scans that benchmark results against the Open Web Application Security Project (OWASP) Top 10 standards.

Streamline patch application through Composer-based workflows using the official magento/quality-patches package. Execute patches systematically via:

After installing a patch, use the Magento admin or Magento admin user interface to refresh the Magento cache for optimal performance and to ensure changes take effect.

For legacy installations, utilize n98-magerun2’s patch module:

Integrate these workflows into your version control hooks to prevent deployment of unpatched systems.

Note! Always ensure your tools and Magento installation are updated to the latest version to benefit from improved security, performance, and compatibility.

Adopt the Magento Security Scan Tool (free Adobe service) that performs automated PCI DSS compliance checks and identifies missing security headers.
