CVE-2026-14763 Overview
CVE-2026-14763 is a SQL injection vulnerability in code-projects Hotel and Tourism Reservation 1.0. The flaw resides in the /admin/tour_reserves.php file, which is part of the Tour Reservations Page component. Attackers can manipulate the tour parameter to inject arbitrary SQL statements into backend database queries. The vulnerability is remotely exploitable and requires no authentication or user interaction. A public exploit has been disclosed, increasing the likelihood of opportunistic attacks against exposed installations. The weakness is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).
Critical Impact
Unauthenticated remote attackers can inject SQL statements through the tour parameter, potentially exposing reservation data, administrative credentials, or the underlying database contents.
Affected Products
- code-projects Hotel and Tourism Reservation 1.0
- Component: Tour Reservations Page (/admin/tour_reserves.php)
- Vulnerable parameter: tour

Technical Details for CVE-2026-14763
Vulnerability Analysis
The vulnerability affects the administrative Tour Reservations Page in code-projects Hotel and Tourism Reservation 1.0. Attackers send crafted HTTP requests to /admin/tour_reserves.php with a malicious value in the tour parameter. The application concatenates this value directly into a SQL query without proper sanitization or parameterization. As a result, the database engine executes attacker-supplied SQL alongside the intended query.
A public exploit has been disclosed through a GitHub SQL Injection Advisory and cataloged by VulDB CVE-2026-14763. The EPSS model estimates a 0.269% probability of exploitation in the next 30 days, placing the CVE in the 18.5th percentile.
Root Cause
The root cause is improper neutralization of user-controlled input passed to a SQL statement. The tour request parameter is inserted into a query string without prepared statements, parameter binding, or input validation. The application trusts client-supplied data during database query construction, which enables injection of arbitrary SQL syntax.
Attack Vector
Exploitation is performed over the network against a reachable web server hosting the vulnerable PHP application. The attacker crafts a request targeting /admin/tour_reserves.php and supplies a malicious tour value that alters the query logic. Because the endpoint is exposed without authentication controls in the vulnerable path, remote attackers can trigger the flaw directly. Common exploitation techniques include UNION-based extraction, boolean-based blind injection, and time-based blind injection to enumerate database contents.
No verified proof-of-concept code is reproduced here. Refer to the GitHub SQL Injection Advisory for the disclosed technical details.
Detection Methods for CVE-2026-14763
Indicators of Compromise
- HTTP requests to /admin/tour_reserves.php containing SQL metacharacters such as single quotes, UNION, SELECT, SLEEP(, or -- in the tour parameter.
- Web server access logs showing unusually long or URL-encoded tour values from unfamiliar source IPs.
- Database error messages or query timeouts correlated with requests to the Tour Reservations Page.
- Unexpected outbound queries or data exfiltration from the database server hosting the reservation application.
Detection Strategies
- Deploy web application firewall (WAF) rules that inspect the tour parameter for SQL injection signatures.
- Enable database query logging and alert on queries originating from tour_reserves.php that contain concatenated user input patterns.
- Correlate HTTP 500 responses from /admin/tour_reserves.php with subsequent database anomalies using SIEM analytics.
Monitoring Recommendations
- Baseline normal traffic to the /admin/ path and alert on volume spikes or scanner-like user agents.
- Monitor authentication events on the underlying database account used by the web application for privilege escalation attempts.
- Track outbound network connections from the web server to detect data staging or exfiltration following exploitation.
How to Mitigate CVE-2026-14763
Immediate Actions Required
- Restrict network access to /admin/tour_reserves.php using IP allowlists, VPN, or reverse-proxy authentication until a fix is applied.
- Deploy WAF rules that block SQL injection payloads targeting the tour parameter.
- Audit the database account used by the application and reduce its privileges to the minimum required for reservation operations.
- Review web and database logs for prior exploitation attempts against the vulnerable endpoint.
Patch Information
At the time of publication, no official vendor patch is listed in the NVD entry for CVE-2026-14763. Consult the code-projects site and the VulDB entry for updated remediation status. Administrators should replace vulnerable query construction with parameterized statements using PDO or mysqli prepared statements, and validate that tour is a numeric or expected value before use.
Workarounds
- Apply server-side input validation that constrains tour to expected data types such as integers.
- Refactor the vulnerable query to use parameter binding rather than string concatenation.
- Disable or remove the Tour Reservations administrative endpoint if it is not required in production.
- Rotate database credentials and reservation administrator passwords after remediation to invalidate any material harvested via prior exploitation.
