WPScan is a Ruby-based CLI security scanner for WordPress sites. It detects vulnerabilities in WordPress core, plugins, and themes, enumerates users and misconfigurations, and supports password brute-force attacks. The architecture follows a controller/finder pattern: controllers orchestrate scan phases (version detection, enumeration, password attack), and finders implement passive/aggressive detection strategies for specific items (plugins, themes, users, backups, etc.). HTTP client is a singleton wrapping Typhoeus with caching, throttling, and proxy support. Vulnerability data is retrieved from the WPScan API or local enterprise database dumps. The codebase is well-structured with clear separation of concerns, extensive test coverage, and support for multiple output formats (CLI, JSON, SARIF). It is actively maintained and regularly updated to keep pace with WordPress ecosystem changes.
JSPrintManager is a client-side printing and scanning solution enabling web applications to bypass browser print dialogs by communicating with a native client application via WebSocket. The system consists of a core JavaScript library (JSPrintManager.js) that provides APIs for creating print/scan jobs, managing printer connections, and handling device-specific communication protocols (serial, USB, Bluetooth, TCP/IP, HID, IPP). A React-based demo application showcases features including printing various file formats (PDF, images, Office documents), raw printer command languages (ZPL, ESC/POS), bidirectional device communication, printer monitoring, and scanning functionality. The solution requires installation of a lightweight native client on user machines to establish the WebSocket bridge between browser and hardware devices.
