What it is

⚡ Sensitive data could slip through the cracks! The Ultimate Member Widgets for Elementor allows embedded sensitive information to be sent without proper safeguards—like mailing personal secrets without sealing the envelope. 🔥 Think of it like a restaurant that sends out takeout orders without properly packaging the food. If the box isn’t sealed, everyone can see what you ordered, and that’s exactly what’s happening with your sensitive data here! An attacker could exploit this flaw to retrieve sensitive information inadvertently included in the responses. This could lead to unauthorized access to personal details, potentially damaging both user trust and your brand's reputation. It's a breach waiting to happen!
