⚡ An authenticated attacker can upload any file they want through the Alex Reservations plugin, putting your WordPress site at serious risk! 🚨 Think of it like a restaurant kitchen where only chefs with the right badges can enter. If those chefs can bring in ingredients without checks, they could introduce something dangerous to the menu without anyone noticing! This vulnerability allows an attacker with Administrator-level access to upload malicious files, potentially leading to remote code execution. Imagine someone sneaking in a toxic ingredient that could compromise the entire kitchen's operations, wreaking havoc on your site and data.
