⚡ A missing capability check on a REST API endpoint could let an unauthorized attacker snag sensitive user data from your WordPress site — no login needed! 🔥 Think of this as a restaurant with a menu that doesn’t require you to place an order first. Anyone can just walk in, grab a free meal, and even take home leftovers — and in this case, that leftovers include users' password hashes! An attacker could easily access sensitive user metadata, including password hashes, putting your users' accounts at serious risk. This unauthorized access could lead to account takeovers and significant data breaches, potentially jeopardizing your entire site’s reputation!
