Back on March 26 of this year, When Magento has released the update of PRODSECBUG-2198 to prevent SQL injection Vulnerability in Magento 2. Before it offers an open invitation to all the hackers to break the store’s important customer and payment data. To prevent your business data from being hacked, it is important for you to fix this core issue before you being targeted.
However, this security enhancement comes as a fix for Magento 2.2.3 as well as Magento 2.2.10 by fixing remote code execution as well as cross-site scripting on your site. Because Magento has already ended support for 2.1.x, they are not going to release a security update for that version.
This Security Patch named PRODSECBUG – 2198 contains a fix for proof-of-concept (POC) exploits, SQL Injection vulnerability to enhance the security of your E-commerce sites! This means as a store owner you should patch or upgrade your store to the latest security patch version to stay safe. Let us secure your Magento store with our SUPEE installation Service or Magento Version Upgrade Service if you are already in a plan to upgrade your Magento store to the latest.
However, Magento always recommends store owners to keep their Magento store up to date with their latest release. But if they are not willing to update their store, they can install such SUPEE to prevent their store from such security Vulnerability.

Method 3: Composer
To resolve the same thing with file from being a patch in your vendor directory, you can create a custom file for that.

In our Magento root, we have a patches/composer directory which is where we reference them and in the extras/patches section, we tell it which Magento module to patch.
That’s it. You have successfully installed Security Patch PRODSECBUG-2198 in Magento 2.
