An attacker could gain unauthorized access to the site’s database, steal sensitive information, and manipulate site content. In another case, an unpatched cross-site scripting vulnerability could be exploited to execute malicious scripts in the context of a user’s browser, potentially leading to session hijacking or phishing attacks.
