What it is

🚨 A crafty admin can open a door to disaster! Magento versions 2.4.1 and earlier are vulnerable to a sneaky XML injection that grants authenticated attackers a backstage pass to execute arbitrary code. 🔥 Think of it like a restaurant where a waiter can slip a hidden note into the kitchen orders, allowing them to make secret substitutions without the chef noticing. This vulnerability lets an attacker manipulate the product layout updates like a rogue chef sneaking in unapproved ingredients! If exploited, an attacker with admin console access could run any code they desire, potentially compromising the entire store. Imagine the chaos of unauthorized changes to product listings or customer data being tampered with – absolutely devastating for your business and your customers!
