⚠️ A crafty image could slip right past the curtains! A missing bounds check in WhatsApp’s image blurring code could allow malicious images to wreak havoc, especially in versions prior to v2.21.22.7. 🚨 Think of this like a restaurant where the chef accidentally leaves the door to the kitchen open. A mischievous customer could toss in something unsavory without anyone noticing, causing chaos before it's even discovered! An attacker could potentially send a malicious image that leads to an out-of-bounds write, resulting in unexpected behavior or crashes in the app. While we’re not looking at anything catastrophic at the moment, the possibility for disruption is still concerning!
