What it is

🚨 Improper path sanitization opens a gaping hole! Archives with sneaky relative paths can write files anywhere, potentially overwriting crucial system data. 🔥 Think of this vulnerability like a delivery service that ignores the 'no trespassing' signs and just drops off packages wherever they please, including sensitive areas where they shouldn't go. It’s a recipe for chaos! With this exploit, an attacker could overwrite critical files on your system, leading to major data loss or service disruption. Imagine your database getting erased because a rogue archive decided to deliver its contents right into your core directory! Using this flaw could lead to a total system meltdown — absolutely devastating!
