Proof of Concept (PoC)

Code or a demonstration created to prove that a specific vulnerability is genuinely exploitable, typically without the full weaponization needed for a real attack. Public release of a PoC can significantly accelerate real-world exploitation, since it lowers the skill barrier for other attackers to build a working exploit.
