Open Redirect is a web security vulnerability that occurs when an application incorrectly or unsafely redirects users to a URL specified by the attacker. This flaw is exploited by attackers to redirect users from a trusted website to a malicious website without their knowledge or consent. Such redirection can lead to phishing attacks, theft of sensitive information, or distribution of malware, as users are more likely to trust the URL if it initially appears to be from a legitimate source.
The vulnerability typically arises when an application takes user-supplied input to determine the destination of a redirect without properly validating or sanitizing that input. For example, an attacker could craft a URL that includes a legitimate website's redirect parameter but points to a malicious site. When a user clicks on this link, they believe they are navigating to a safe location, but are instead sent to a site controlled by the attacker.
