GMSGadget, or Give Me a Script Gadget, is a curated set of JavaScript tools designed to bypass web security measures like Content Security Policy (CSP) and HTML sanitizers, including DOMPurify. The tools listed are not exploits themselves; they consist of either vulnerabilities that have been patched or standard JavaScript behaviors that can be manipulated to circumvent restrictions imposed by web applications. The platform encourages community involvement, inviting users to contribute by submitting new gadgets, enhancing existing documentation, or reporting any issues. There are clear guidelines for participation, making it accessible for those interested in improving the resource. This collaborative approach aims to keep the collection relevant and up-to-date in the evolving landscape of web security.
