Improper Input Validation
Adobe Commerce and Magento Open Source in versions prior to 2.3.7-p3, and 2.4.x prior to 2.4.3-p2 are affected by an Improper Input Validation vulnerability during the checkout process. Exploitation of this issue does not require user interaction and could result in arbitrary code execution. There are no fixed releases but Adobe published several patch files that fix the vulnerability. These patch files need to be manually applied to the vulnerable versions.
