CVE-2026-14688: SQL Injection in itsourcecode Online Hotel Management System 1.0

Technical summary

The vulnerability exists in the /admin/login.php file where user-supplied input from the email parameter is not properly sanitized before being used in SQL queries. This classic SQL injection weakness (CWE-89) combined with improper input validation (CWE-74) allows an unauthenticated attacker to craft malicious email values that manipulate the SQL query logic. The attack requires no special privileges or user interaction, making it trivial to exploit over the network. The CVSS 3.1 score of 7.3 (HIGH) reflects the combination of confidentiality, integrity, and availability impacts possible through database manipulation.

Business impact

A successful exploit could allow attackers to extract sensitive guest and booking data, modify or delete records, or potentially escalate privileges within the hotel management system. For hotel operators, this could result in guest privacy violations, service disruption, booking fraud, or reputational damage. Organizations running this software may face compliance violations if guest data is accessed without authorization.

Affected systems

itsourcecode Online Hotel Management System version 1.0 is affected. Organizations should identify all instances of this product deployed in their environments, particularly any exposed to untrusted networks or the internet. Verify your deployment version against the vendor documentation.

Exploitability

Exploitability is high due to three critical factors: the vulnerability requires no authentication, no special user interaction, and no complex attack setup. The attack surface is the login page itself, accessible to any network user. The public availability of proof-of-concept code significantly increases the likelihood of weaponization by malicious actors and opportunistic scanning.

Remediation

Immediate action is required. Upgrade to a patched version released by itsourcecode once available. In the interim, implement network access controls to restrict access to /admin/login.php to trusted IP ranges, deploy a Web Application Firewall (WAF) with SQL injection detection rules, and monitor database query logs for suspicious activity. Apply prepared statements and parameterized queries in any custom integrations.

Patch guidance

Contact itsourcecode to confirm availability of a security patch for version 1.0. Verify patch version numbers and release dates directly from the vendor advisory before deployment. Test patches in a non-production environment first. Until a patch is available, prioritize network segmentation and WAF rules as compensating controls.

Detection guidance

Monitor for SQL injection attempts in web server and application logs targeting /admin/login.php, particularly patterns containing SQL keywords, comment sequences (-- or /*), or boolean logic operators in email parameters. Review database access logs for unusual query patterns or privilege escalations from the application's database user. Implement WAF logging to detect and block SQL injection payloads in real time.

Why prioritize this

This vulnerability warrants high priority remediation due to its unauthenticated, network-accessible nature, public exploit availability, direct impact to sensitive data, and the ease of exploitation requiring minimal attacker sophistication. The admin login page is a critical security boundary, and its compromise undermines all downstream security controls.

Risk score, explained

The CVSS 3.1 score of 7.3 (HIGH) reflects: network accessibility (AV:N), low attack complexity (AC:L), no privilege requirements (PR:N), no user interaction needed (UI:N), and impacts to confidentiality, integrity, and availability of the affected system. This combination places the vulnerability in the HIGH severity tier, warranting urgent attention.
