CVE-2025-0531

CVE-2025-0531 is a critical SQL injection vulnerability in code-projects Chat System 1.0, affecting the processing of the /user/leaveroom.php file. The issue arises from improper handling of the 'id' argument, allowing manipulation that leads to SQL injection as classified under CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection).

The vulnerability can be exploited remotely by attackers with low privileges, such as authenticated users, due to the low attack complexity and lack of required user interaction. Successful exploitation enables limited confidentiality, integrity, and availability impacts through SQL injection, potentially allowing unauthorized data access, modification, or disruption within the chat system's database.
