Apply patches with composers post-install-cmd

magento2_teaser_patch

I just want to introduce another approach that will apply Magento patches, in case your Magento instance isn’t hosted on Adobe’s Cloud infrastructure or can’t be applied as explained in How to apply a composer patch provided by Adobe for some reason.

1. Update your composer.json file

Add a new section scripts” at the end of your composer.json file and validate your file with composer validate.

If you see ./composer.json is valid you are good to move on. Btw. your composer.lock file doesn’t need to be updated.

2. Create a folder ./patches/

Create a folder ./patches/ or something similar and copy your *.patch file in there.

3. Test it

Run composer install and wait. Your script and patch should be executed after Generating autoload files just like in the below output.

4. Deploy it

Commit your changes ( composer.json and ./patches/ ) folder and run your deployment procedure.

That’s it!

Adobe APSB22-12 – Don’t panic!

magento2_teaser_patch

Adobe has released a critical security patch early this week on https://support.magento.com/hc/en-us/articles/4426353041293-Security-updates-available-for-Adobe-Commerce-APSB22-12– and https://helpx.adobe.com/security/products/magento/apsb22-12.html.

Of course, Adobe Commerce merchants and agencies are nervous and want to apply the security patch as soon as possible. However, I believe as long as your admin passwords are strong enough and you have control about your admin accounts, you shouldn’t be worried too much.

Here is why.

Let’s have a look at the content of the security patch.

The patch will update two files only that are responsible to process template variables such as email variables {{var logo_url}} or {{config path=”general/store_information/name”}} or variables within CMS pages or Static Blocks. The change is trivial and will wipe out unwanted content by using the pattern $pattern = ‘/{{.*?}}/’.

It basically means, in order to be able to exploit this issue, you must:

1. Know the admin url of a store
2. Have access to the Magento backend ( ideally admin privileges )
3. Know how to exploit the issue

So, as long as you maintain admin accounts regularly and know who is actively working in your backend, you should be fine.

However, if you have modules installed that add custom variables by injecting Magento\Email\Model\Template\Filter in combination with 3rd party services, you should probably go and install the patch with your next release.

Update: 2022/02/16

Code could possibly injected by using the customers billing or shipping address ( e.g {{trans “%name,” name=$order.getBillingAddress().getName()}} ) depending on how strong form validation is in the front-end ( My Account > Addresses or Checkout ).

Broken Admin Panel after SUPEE-8788

After the installation of patch SUPEE-8788 in Magento 1.9.0.1 I have experienced a broken product edit form in Catalog > Manage Products > { select any product } > Edit Product. Every time when I tried to edit a product it was logging the following error message.

I have found a community extension in my project which was causing the problem by rewriting the complete class Mage_Catalog_Helper_Image. With diff I was able to identify all changes which I needed to copy from core to the community extension.

I just added the missing constant

and updated the method validateUploadFile().
