CVE-2025-55444 is a SQL injection vulnerability identified in the 'id2' parameter of the cancel_booking.php page within the Online Artwork and Fine Arts MCA Project 1.0 application. SQL injection vulnerabilities occur when user-supplied input is improperly sanitized, allowing attackers to inject malicious SQL queries into the backend database. In this case, the vulnerability enables a remote attacker to manipulate the 'id2' parameter to execute arbitrary SQL commands. This can lead to unauthorized database enumeration, exposing sensitive data such as user information, booking details, or financial records. Furthermore, the vulnerability may escalate to remote code execution if the attacker can leverage the database server's capabilities or underlying system commands, potentially allowing full system compromise. The vulnerability is remotely exploitable without authentication, increasing its risk profile. Although no specific affected versions or patches are listed, the vulnerability is publicly disclosed as of August 20, 2025, with no known exploits in the wild yet. The lack of a CVSS score suggests the need for an independent severity assessment based on the described technical details.

For European organizations, especially those involved in the online artwork, fine arts, or cultural sectors using this MCA Project 1.0 application, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to sensitive customer and transactional data, violating GDPR requirements and potentially resulting in heavy fines and reputational damage. The potential for remote code execution further elevates the threat, as attackers could gain persistent access to internal networks, disrupt services, or exfiltrate intellectual property. Given the cultural and economic importance of art institutions and galleries in Europe, a successful attack could also undermine trust in digital platforms facilitating art sales and bookings. Additionally, the remote and unauthenticated nature of the vulnerability means attackers can exploit it at scale, increasing the risk of widespread impact across multiple organizations using the affected software.

Organizations should immediately conduct a thorough code review of the cancel_booking.php page, focusing on the 'id2' parameter to ensure proper input validation and sanitization. Implementing parameterized queries or prepared statements is critical to prevent SQL injection. If possible, restrict database user privileges to the minimum necessary to limit the impact of any injection attempts. Network-level protections such as Web Application Firewalls (WAFs) should be configured to detect and block SQL injection patterns targeting this parameter. Since no official patches are available, organizations should consider isolating or disabling the vulnerable functionality temporarily until a secure update is released. Regular security testing, including automated vulnerability scanning and manual penetration testing, should be performed to detect similar injection flaws. Additionally, monitoring database logs for unusual query patterns can help identify exploitation attempts early. Finally, organizations must ensure compliance with data protection regulations by preparing incident response plans addressing potential data breaches stemming from this vulnerability.
