    Exploitarium

    Exploitarium

    A single archive of public exploit PoCs and vulnerability research

    ...It gathers older standalone research repositories into one place while also adding newer entries as self-contained folders. The project includes tracked examples involving software such as 7-Zip, AnyDesk, c-ares, curl, Discourse, Docker, and other targets. Its purpose is research visibility, vulnerability study, and educational review rather than normal application deployment. Because the repository contains exploit proof-of-concepts, it should only be used in authorized labs, defensive analysis, or coordinated research contexts. It is best categorized as a high-risk security research archive that requires careful legal and ethical handling.
