Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-4237 is a SQL injection vulnerability (CWE-74, CWE-89) in itsourcecode Free Hotel Reservation System 1.0. The issue affects unknown code in the file /hotel/admin/mod_reports/index.php, where manipulation of the "Home" argument enables the injection. Published on 2026-03-16, it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), rated as high severity.

Remote attackers require no privileges or user interaction to exploit this flaw over the network with low complexity. Successful exploitation can result in limited impacts to confidentiality, integrity, and availability, such as unauthorized data access, modification, or disruption via injected SQL payloads.

Advisories from VulDB (ctiid.351179, id.351179, submit.771243) document the vulnerability, and a related GitHub issue in silver-guide provides further details. The vendor site at itsourcecode.com may offer updates, though no specific patches are detailed in the available information.

An exploit has been publicly disclosed and may be actively used, heightening the risk for unpatched deployments of this system.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover SQLi flaws before deployment but does not stop their introduction.

SI-10 Information Input Validation good match

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles require parameterized queries and input sanitization that structurally eliminate SQLi.

SI-4 System Monitoring partial match

System monitoring can identify attempted SQLi exploitation via anomalous queries after the weakness exists.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and output encoding that prevent injection flaws.

PR.AT-02 partial match
prevents

Training raises developer awareness of SQLi risks and can reduce introduction likelihood (partial) but removes none of the actual coding flaw's risk by itself since technical neutralization is still required.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches injection vulnerabilities before release.

A.5.6 Contact with special interest groups partial match
prevents

Early warnings and shared best-practice information help organizations apply the latest remediation techniques against SQL-injection vulnerabilities.

A.5.7 Threat intelligence partial match
prevents

Threat-intelligence feeds that surface new SQL-injection campaigns enable rapid updates to query-construction defenses and detection signatures before exploitation occurs.

A.8.15 Logging partial match
finds

Logging supports detection of injection attempts but does not prevent the weakness.

A.8.16 Monitoring activities partial match
finds

Monitoring activities can identify active injection attacks after they occur.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and output encoding that directly prevent injection flaws.
