XSS Challenge Wiki is an archived community knowledge base documenting solutions and results from cross-site scripting challenges. It was created to preserve techniques uncovered through security puzzles that were otherwise scattered across separate sites and events. The wiki contains pages for Cure53 challenges, H5SC mini challenges, ES6 puzzles, CSP exercises, JSON hijacking tasks, and other historical competitions. Many entries explain challenge constraints, successful approaches, and lessons for penetration testers. A separate index helps readers find past and current challenges without immediately viewing solution spoilers. Community participation originally expanded the archive through edits, issues, and contributions. The repository became read-only in 2023 and now serves primarily as a historical defensive research resource.
