🚨 A stored XSS vulnerability in Homarr could let attackers add themselves as admins just by exploiting a malicious SVG file—no cape needed! ⚡ Think of this like a sneaky delivery person who slips a forged package into a company’s supply chain. Instead of delivering the expected order, they drop in something designed to open the door for them to take control inside the business. If an administrator views the compromised SVG file, the attacker can gain full administrative access to the dashboard, allowing them to wreak havoc—think of it as having the keys to the kingdom and changing the locks! This could lead to unauthorized changes, data leaks, or even complete takeovers of the system.
