If your business sells products through Adobe Commerce or Magento, this is not an update to leave on next month’s maintenance list.
On September 7, 2026, Adobe released an emergency security hotfix for a critical vulnerability identified as CVE-2026-75650. Adobe says attackers are already exploiting the weakness. One day later, CISA added it to its Known Exploited Vulnerabilities Catalog, which is reserved for security problems supported by evidence of real-world attacks.
The vulnerability can allow an attacker to run unauthorized commands on a vulnerable website without first signing in. Adobe assigned it a severity score of 10 out of 10.
That does not mean every Adobe Commerce or Magento store has been compromised. It does mean affected businesses should confirm their protection immediately rather than assuming routine updates have already handled it.
Your online store is more than a website. It may connect to customer accounts, orders, inventory, shipping tools, payment services, and marketing systems.
If an attacker gains control of the website, the potential consequences can include:
A small business may not manage Magento directly. The website could be maintained by a developer, hosting company, marketing agency, or outside IT provider. The important question is not whether you personally know how to install the hotfix. It is whether someone clearly owns that responsibility and can confirm the work was completed.
Ask your website provider these direct questions:
Request a written answer. “Updates are automatic” or “the site looks fine” is not the same as confirming that this specific hotfix was installed.
Installing the hotfix closes the known security opening. It does not automatically prove that nobody used the opening before it was closed.
The website administrator or security provider should also review the environment for unusual activity, such as:
These checks should be performed by someone familiar with the website’s normal configuration. Avoid making numerous changes if compromise is suspected, since that can make the incident harder to understand.
This incident is also a good reason to review who can administer the website.
Each authorized person should have an individual account. Shared administrator passwords make it difficult to determine who changed something and create problems when an employee or vendor leaves.
Administrator accounts should use strong, unique passwords and multifactor authentication wherever it is supported. Old agency, contractor, and employee accounts should be removed promptly.
Before a major website update, a current backup should be available. After the hotfix is installed, the provider should test important business functions, including:
A backup is only valuable when it can be restored. Businesses should know where their website backups are stored, how often they run, and who is responsible for recovery.
Security incidents often expose an ownership problem rather than a purely technical problem. The business owner thought the developer was handling updates, the developer thought the hosting company was handling them, and nobody was checking the results.
Create a simple website responsibility list covering updates, backups, security monitoring, administrator access, emergency contacts, and renewal dates. Review it with every company that helps manage the site.
