A PoC (proof of concept) is a practical demonstration used to verify whether a security flaw can be exploited and assess its impact.

Background for this topic.
PoC means “proof of concept”: a limited demonstration that a technical idea works. In information security, the term most often describes code or steps showing that a reported vulnerability can be triggered or exploited, although it can also mean a benign prototype used to test a defensive design. A PoC helps researchers, vendors, and defenders reproduce a finding, assess affected configurations, and distinguish a plausible issue from one demonstrated in practice.
A PoC is evidence of exploitability, not proof that every deployment is vulnerable or that compromise is reliable. Security teams should test it in an isolated environment, verify prerequisites and impact, and use the results to prioritize remediation. Public release can accelerate validation and patch development, but detailed exploit code may lower the effort required for misuse—especially before fixes are broadly available. Vulnerability reports should therefore protect sensitive details during coordinated disclosure and update the assessment if a PoC becomes a practical exploit.
