SQL Injection Found in Hotel Management System

A critical SQL injection vulnerability, tracked as CVE-2026-6142, has been identified in tushar-2223’s Hotel Management System. According to the National Vulnerability Database, the flaw exists within the /admin/roomdelete.php file, specifically through the manipulation of the ID argument. This isn’t some obscure edge case; it’s a direct SQLi that could lead to serious data compromise.

The National Vulnerability Database (NVD) notes this vulnerability carries a CVSS score of 7.3 (HIGH), indicating a significant risk. What makes this particularly nasty is that remote exploitation is possible, and an exploit is already publicly available. This means attackers don’t need local access; they can hit this system from anywhere, and the blueprint for the attack is out there for anyone to use. The vendor, unfortunately, hasn’t responded to the issue report, which is a major red flag given the severity and public exploit.

Adding to the complexity, the product uses a rolling release model, so pinpointing exact affected versions is tricky. This continuous delivery approach means security teams might struggle to determine if their specific deployment is patched or still vulnerable. The NVD highlights CWE-74 (Improper Neutralization of Special Elements in Output Used by a Different Context) and CWE-89 (Improper Neutralization of Special Elements used in an SQL Command (‘SQL Injection’)) as the underlying weaknesses, which are classic indicators of poor input validation.
