CVE-2026-2553 identifies a SQL injection vulnerability in the tushar-2223 Hotel-Management-System, specifically within the /home.php file's HTTP POST request handler. The vulnerability arises from improper sanitization or validation of user-supplied input in the Name and Email parameters, allowing attackers to inject malicious SQL queries. Exploitation requires no authentication or user interaction and can be performed remotely, making it accessible to a wide range of threat actors. The affected product employs continuous delivery with rolling releases, complicating precise version identification and patch management. The vendor has not issued any response or patch, and no official fixes are currently available. The CVSS 4.0 base score is 5.3 (medium), reflecting the moderate impact and ease of exploitation without privileges. Public exploit code has been released, increasing the likelihood of attacks. The vulnerability can compromise confidentiality by exposing sensitive data, integrity by altering database contents, and availability by potentially disrupting service. The lack of vendor response and patch availability increases the urgency for organizations to implement compensating controls.

The SQL injection vulnerability allows attackers to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized disclosure of sensitive customer and business data, unauthorized modification or deletion of records, and disruption of hotel management services. This can result in data breaches affecting customer privacy, financial losses, reputational damage, and regulatory non-compliance for organizations using the affected system. Since the attack requires no authentication and can be launched remotely, the attack surface is broad, increasing the risk of widespread exploitation. The continuous delivery model without clear versioning complicates patch management, potentially prolonging exposure. Organizations may face operational disruptions if attackers leverage the vulnerability to corrupt or delete critical data. The public availability of exploit code further elevates the threat level by enabling less skilled attackers to exploit the flaw.

Given the absence of official patches or vendor response, organizations should immediately implement input validation and sanitization controls at the web application firewall (WAF) or reverse proxy level to block malicious SQL payloads targeting the Name and Email parameters. Employ parameterized queries or prepared statements in any custom integrations or extensions to the system if possible. Conduct thorough code reviews and penetration testing focused on input handling in /home.php and related components. Monitor database and application logs for unusual query patterns or errors indicative of SQL injection attempts. Restrict database user privileges to the minimum necessary to limit the impact of potential exploitation. Consider isolating the affected system within segmented network zones to reduce exposure. If feasible, migrate to alternative hotel management solutions with active vendor support. Maintain regular backups of critical data to enable recovery from potential data corruption or deletion. Stay alert for any future vendor updates or community patches addressing this vulnerability.
