CVE-2026-14762: SQL Injection in Hotel and Tourism Reservation 1.0 Admin Panel

Technical summary

CVE-2026-14762 is a unauthenticated remote SQL injection vulnerability affecting code-projects Hotel and Tourism Reservation 1.0. The vulnerability exists in the Room Management Page component (/admin/rooms.php) where user-supplied input in the 'delete' parameter is not properly sanitized before being incorporated into SQL queries. The attack requires no authentication, no special configuration, and no user interaction. The vulnerability impacts confidentiality, integrity, and availability of the underlying database through classic SQL injection techniques (CWE-89) enabled by improper input validation (CWE-74).

Business impact

Exploitation of this vulnerability could allow attackers to exfiltrate guest information, reservation records, payment data, and other sensitive business information from the hotel system database. Attackers may also modify or delete reservation data, causing operational disruption and customer service failures. The ability to corrupt data without detection creates compliance risks related to data protection regulations and fraud liability. Hotels using this system face potential reputation damage, guest notification requirements, and regulatory penalties depending on the nature of data compromised.

Affected systems

code-projects Hotel and Tourism Reservation version 1.0 is affected. Organizations running this software should immediately identify all deployed instances, particularly those exposed to network access. The vulnerable component is the administrative interface, meaning systems with exposed /admin/ directories are at higher risk. No vendor patch information is currently available; verify directly with the vendor regarding patch status and timeline.

Exploitability

This vulnerability has a CVSS v3.1 score of 7.3 (HIGH) reflecting the combination of remote exploitability without authentication and direct impact on data confidentiality, integrity, and availability. The attack vector is network-based, the attack complexity is low, and no privileges or user interaction are required. The fact that public exploits now exist significantly increases practical exploitation risk. Attack surface is high for any organization with internet-facing or internal network access to the /admin/rooms.php endpoint.

Remediation

Immediate actions: (1) Identify all instances of Hotel and Tourism Reservation 1.0 in your environment, including test and development systems. (2) Restrict network access to the /admin/ directory using firewall rules, WAF policies, or reverse proxy authentication until a patch is available. (3) Isolate affected systems from internet exposure if operationally feasible. (4) Monitor database activity for suspicious SQL queries. Contact the vendor (code-projects) immediately for patch availability and timelines. If no patch is forthcoming, evaluate alternative hotel management systems. Apply vendor patches immediately upon release.

Patch guidance

No patch version information is currently available from vendor advisories for this vulnerability. Contact code-projects directly to request patch availability and expected release timelines. Do not delay remediation while waiting for a patch; implement access controls and monitoring as interim mitigations. When patches are released, prioritize testing and deployment to affected systems within 24-48 hours given the public exploit availability and HIGH severity rating.

Detection guidance

Monitor /admin/rooms.php access logs for suspicious patterns, particularly requests containing SQL syntax keywords (SELECT, UNION, DROP, DELETE, INSERT) in the 'delete' parameter. Enable database query logging and alert on failed queries, error messages, or unusual query patterns. Web application firewalls should be configured to block or alert on common SQL injection payloads targeting the delete parameter. Review access logs for any successful administrative changes made without corresponding user actions. Monitor for unusual data access patterns, mass deletion events, or data exfiltration from the reservation database.

Why prioritize this

This vulnerability warrants immediate prioritization due to: (1) HIGH CVSS severity (7.3) with unauthenticated remote attack vector, (2) public exploit availability reducing the barrier to attack, (3) direct impact on sensitive guest and business data, (4) lack of authentication requirement, (5) operational impact through potential data corruption. Organizations should treat this as a critical remediation item, particularly if the affected system is internet-accessible or handles production reservation data.

Risk score, explained

The CVSS v3.1 score of 7.3 (HIGH) reflects: Network attack vector (AV:N) with no prerequisites for remote exploitation, Low attack complexity (AC:L) with straightforward SQL injection techniques, No privilege requirements (PR:N) to trigger the vulnerability, No user interaction (UI:N) needed, and Unchanged scope (S:U) with direct impact to the affected system. The vulnerability affects all three security objectives: Confidentiality (read data), Integrity (modify data), and Availability (delete data). The score appropriately reflects the severity of unauthenticated SQL injection in a business-critical system, though organizations should escalate priority further given active public exploitation.
