WooYun Legacy is a Claude Code security plugin that enriches defensive security analysis with historical vulnerability data from the WooYun platform. Its knowledge base is derived from 22,132 publicly documented business-logic vulnerability cases collected between 2010 and 2016. Rather than teaching new exploitation techniques, it adds real cases, statistics, recurring patterns, and data-driven priorities to security reports. The repository organizes information into methodology references, technical knowledge, vulnerability categories, examples, and evaluation data. A lightweight installation provides condensed indexes, while the full repository exposes the complete case collection for deeper research. It is intended for authorized testing, risk analysis, code review, and defensive security work. The maintainers have stated that the project is no longer actively maintained.
