⚡ A simple tweak to the query parameter userId is all it takes to peek into someone else's order history! Imagine a busy restaurant where anyone can swap their order number with a friend's; suddenly, you have access to their meal choices and special requests — and without any verification! This vulnerability allows attackers to access arbitrary order details of other users, potentially exposing sensitive information such as personal addresses, payment details, and purchase history. It's like leaving the doors of a vault open, inviting anyone to stroll in and take what they want!
Imagine a busy restaurant where anyone can swap their order number with a friend's; suddenly, you have access to their meal choices and special requests — and without any verification!

This vulnerability allows attackers to access arbitrary order details of other users, potentially exposing sensitive information such as personal addresses, payment details, and purchase history. It's like leaving the doors of a vault open, inviting anyone to stroll in and take what they want! To mitigate this vulnerability, update xmall to version 1.1.1 or later, where access controls are correctly implemented. Additionally, review your API endpoints to ensure all sensitive data is protected by strict authorization checks. You’ve got this! Follow these steps to secure your system and protect user data. 🛡️
