⚠️ A prototype pollution vulnerability in Popup by Supsystic could let an attacker sneak in arbitrary properties, like adding secret ingredients to a recipe without the chef knowing! 🍽️ Think of it like a restaurant where the waiter can slip in extra items to the menu without the chef's approval — suddenly, new dishes appear that no one ordered. That's how prototype pollution messes with the JavaScript objects in your site! If exploited, an attacker could manipulate the entire JavaScript environment of your WordPress site, potentially leading to unpredictable behavior or even malicious actions that could compromise user data. It’s like having a rogue chef in the kitchen, who can serve up whatever they desire, putting your customers at risk!

That's how prototype pollution messes with the JavaScript objects in your site! This vulnerability allows an attacker to inject properties into `Object.prototype`, which can lead to unexpected behavior in the application due to the altered JavaScript object inheritance chain.
