Think of it as a delivery driver getting access to the locked warehouse where all the valuable packages are stashed.

This flaw arises from incorrect boundary conditions in the Graphics: CanvasWebGL component, allowing a malicious actor to bypass the isolation that sandboxes are supposed to enforce. Essentially, it’s like a poorly built fence that lets anyone stroll right into a secure area.
If exploited, this vulnerability could allow an attacker to escape the confines of the sandbox environment, potentially leading to unauthorized access to sensitive data or system resources.
