What it is

🔥 A crafted GET request is all it takes to unleash chaos! MiniCMS v1.10 has a Cross Site Scripting (XSS) vulnerability that could let attackers execute arbitrary code—yikes! ⚠️ Think of it like a restaurant where a customer can slip a note to the chef with a fake order. If the chef doesn’t double-check the request, they might end up preparing an unexpected—and potentially disastrous—meal for everyone. In this case, attackers can execute their malicious code instead of legitimate requests! The consequences could be absolutely devastating. An attacker could run any code they choose on your server, leading to data theft, website defacement, or worse. This level of access can compromise user information and your site's integrity in just a few clicks!
