Adobe has fixed a critical vulnerability in its e-commerce software that allowed attackers to run their own code on merchants' sites.
The bug, which was being exploited in the wild, affects Adobe Commerce and Magento Commerce, software that allow merchants to host and manage online stores. It is rated critical, with a 9.8 score under the Common Vulnerability Scoring System (CVSS), and is described as improper input validation bug that allows attackers to execute arbitrary code by manipulating input fields.
"Adobe is aware that CVE-2022-24086 has been exploited in the wild in very limited attacks targeting Adobe Commerce merchants," the company warned in an advisory.
The vulnerability affects v2.4.3 and earlier of the Adobe products, and the company has released a patch. With little other information about the bug, there are no clear workarounds for the vulnerability other than to patch systems immediately.
Security bugs like these allow attackers to inject their own code onto e-commerce sites, which could skim a customer's credit card details and login credentials. One of the most popular skimming groups is Magecart, originally a single group that experts have seen morph into multiple groups.
Adobe acquired Magento in 2018 and rebranded its Magento Commerce product as Adobe Commerce. The company still offers a free version called Magento Open Source for building ecommerce stores.
Adobe Commerce offers a page builder for product stores, personalized product recommendations, and real-time inventory management that allows vendors to arrange for home delivery or pickup at the store. It also offers reporting capabilities to help visualize store performance.

The role of payments in digital transformation
In September, Adobe added a new Payment Services tool to the Commerce product that allows merchants to support more payment services, such as Venmo and PayPal.
Security company Malwarebytes recently noted an increase in Magecart activity after one of the groups began targeting large numbers of ecommerce scores. Much of this activity focuses on Magento 1, which has not been supported since 2020. These attackers used a vulnerability in the Quickview plugin to create rogue Magento admin users that could run code with elevated privileges.
