dom-red is a command-line script designed to test multiple domains for open redirect vulnerabilities. The tool accepts a list of domains as input and systematically checks each one for potential open redirect security flaws. Open redirect vulnerabilities occur when a web application accepts user-controlled input that specifies a link to an external site, potentially allowing attackers to redirect users to malicious websites. The script operates from the command line interface, making it suitable for integration into automated security testing workflows. It processes domain lists in batch mode, enabling security professionals to efficiently assess multiple targets for this specific vulnerability type. Upon completion of its scanning process, dom-red reports any identified open redirect vulnerabilities found across the tested domains. This functionality makes it useful for security assessments, penetration testing activities, and routine vulnerability scanning operations.
