CVE-2021-36033Network attack vector

Administrator-level code execution via crafted widget script

Published Sep 1, 2021 · Updated Sep 16, 2024

XML injection in Adobe Commerce Widgets Module 2.4.2, 2.4.2-p1, and 2.3.7 and earlier allows remote authenticated users to execute code. Adobe has not disclosed the Widgets Module code path or how it processes the crafted script to cause XML injection. Administrative access to a network-reachable Commerce instance is required, and successful exploitation executes arbitrary code in the server context.
