Repository matches are links and GitHub-supplied metadata only. They are not verified working proof-of-concept code. Each supported query is bounded to ten pages and at most 1,000 indexed results. This is not a complete index of GitHub or public exploit research. Coverage can also be limited by provider availability, rate limits, rejected metadata, incomplete search results, manual review, and the recorded refresh time.
