Adobe Commerce 2.3.7-p2 is a security release that provides security fixes that enhance your Adobe Commerce 2.3.7 or Magento Open Source 2.3.7 deployment. It provides fixes for vulnerabilities that have been identified in the previous release (Adobe Commerce 2.3.7-p1).
PHP 7.3 reaches end of support in December 2021, and Adobe Commerce 2.3.x and Magento Open Source 2.3.x reaches end of support in April 2022. We strongly recommend planning your upgrade now to Adobe Commerce 2.4.x or Magento Open Source 2.4.x deployment to help maintain PCI compliance.

What’s in this release?
This security patch includes:

This release includes the following hotfixes, which address known issues first identified in Adobe Commerce 2.3.7-p1:
AC-384__Fix_Incompatible_PHP_Method__2.3.7-p1_ce.patch to address PHP fatal error on upgrade. See the Adobe Commerce upgrade 2.4.3, 2.3.7-p1 PHP Fatal error Hotfix Knowledge Base article for information on both patch and issue.
Adobe Commerce 2.3.7-p1 known issue outdated order total for PayPal. See the Adobe Commerce upgrade 2.4.3, 2.3.7-p1 PHP Fatal error Hotfix Knowledge Base article for information on both patch and issue.
Session IDs have been removed from the database. This code change may result in breaking changes if merchants have customizations or installed extensions that use the raw session IDs stored in the database.
Restricted admin access to Media Gallery folders. Default Media Gallery permissions now allow only directory operations (view, upload, delete, and create) that are explicitly allowed by configuration. Admin users can no longer access media assets through the Media Gallery that were uploaded outside of the
wysiwyg directories. Administrators who want to access media assets must move them to an explicitly allowed folder or adjust their configuration settings. See Modify Media Library folder permissions.
Lowered limits to GraphQL query complexity. The GraphQL maximum allowed query complexity has been lowered to prevent Denial-of-Service (DOS) attacks. See GraphQL security configuration.
Recent penetration test vulnerabilities have been fixed in this release.
The unsupported source expression
unsafe-inline has been removed from the Content Security Policy
frame-ancestors directive. GitHub-33101
Issue: Adobe Stock images uploaded into the
<install_dir>/pub/media/catalog directories are not visible in the Media Gallery. Workaround: To view and work with these images, delete them from the filesystem directories and re-upload them into an allowed Media Gallery directory.
