⚠️ A simple paste could bring down your GeoGebra CAS Calculator! An attacker can cause a full application crash with just 8000 repeated characters — talk about overkill! Think of it like a restaurant where a customer keeps ordering the same dish over and over until the kitchen gets overwhelmed and can't cook anymore. That’s exactly how this buffer overflow works; it floods the application with too much data, causing it to crash. If successfully exploited, this vulnerability could disrupt users' calculations and learning experiences, leaving them frustrated and unable to use the tool. While it won't lead to data loss, the denial of service could be absolutely debilitating during crucial study or work sessions.
