🚨 A sneaky lack of validation in the Contact Form Plugin for WordPress means your exported CSV files could be a playground for attackers! 🔥 Think of it like a restaurant that takes your order without checking the ingredients — if a customer sneaks in something toxic that doesn’t get filtered out, everyone could get sick. This plugin exports form data without properly checking for harmful content, leading straight to CSV injection! An attacker could craft entries that, when exported as CSV, execute rogue commands on unsuspecting users’ systems. Imagine a malicious entry that can compromise spreadsheets, potentially leading to data breaches or the spread of malware — absolutely devastating!
