If you’re using Lenderd 1003 Mortgage Application versions up to 1.75, you're at risk. 🔍 Think of this vulnerability like a restaurant where the kitchen prepares any dish based solely on what the waitstaff writes on the order — if a wrong ingredient slips through, it could lead to a disastrous meal! 🥴 An attacker could upload a malicious CSV file that leverages formula execution to manipulate or extract sensitive data, causing chaos for users who mistakenly trust the content. While it might not seem dire at first, the potential for unauthorized data manipulation is nothing to sneeze at!
