How the Vulnerability Works:
CVE-2025-25514 exploits improper input sanitization in SeaCMS v13.3’s admin_collect_news.php component. Attackers craft malicious SQL queries through the ‘keyword’ parameter, which gets directly concatenated into database operations. This allows UNION-based injection to extract sensitive data like admin credentials. The vulnerability stems from missing prepared statements and weak filter bypass techniques using URL encoding.
