4850 vulnerabilities classified as CWE-352 (跨站请求伪造(CSRF)). AI Chinese analysis included.
CWE-352, Cross-Site Request Forgery, is a web application weakness where the system fails to verify that an incoming request was intentionally initiated by the authenticated user rather than an unauthorized actor. Attackers typically exploit this vulnerability by tricking a victim into submitting a malicious request, often via a hidden link or form on a third-party site, while the victim is logged into the target application. Because the browser automatically includes valid session cookies, the server processes the forged request as legitimate, potentially allowing unauthorized actions like fund transfers or profile changes. Developers mitigate this risk by implementing anti-CSRF tokens, synchronizer tokens, or validating the Origin and Referer headers to ensure requests originate from trusted sources, thereby preventing unauthorized state changes.
