CVE-2026-14795: SQL Injection in CodeAstro Apartment Visitor Management System 1.0

Technical summary

CVE-2026-14795 is a SQL injection vulnerability (CWE-89, CWE-74) affecting CodeAstro Apartment Visitor Management System 1.0. The flaw resides in improper input validation of the 'remark' parameter passed to /apartment-visitor/action-visitor.php. The application fails to sanitize or parameterize SQL queries, allowing authenticated users to craft malicious input that breaks out of the intended SQL statement context. The CVSS v3.1 score of 6.3 reflects the authenticated access requirement (PR:L), though network-accessible attack vector and multi-impact potential (confidentiality, integrity, availability) elevate risk within those constraints.

Business impact

Organizations using CodeAstro Apartment Visitor Management System 1.0 face potential data breach of visitor records, unauthorized modification of visitor logs (impacting security audits and compliance), and possible database corruption or denial of service. For property management firms, this could compromise tenant and guest privacy, trigger regulatory compliance violations, and undermine incident investigation capabilities. The authenticated requirement limits blast radius but does not eliminate risk—compromised staff accounts or insider threats represent realistic attack paths.

Affected systems

CodeAstro Apartment Visitor Management System version 1.0 is confirmed affected. No patch version, alternative products, or vendor-provided mitigation has been identified in available disclosures. Organizations should verify their exact product version and deployment context against CodeAstro's advisory. If you operate this software, assume it is vulnerable unless an update has been released post-publication (2026-07-06).

Exploitability

The vulnerability is exploitable by any user with valid application credentials. Public disclosure of proof-of-concept code increases practical exploitation likelihood. Attack complexity is low—standard SQL injection techniques apply. However, the authenticated prerequisite means threat actors must first obtain valid login credentials, either through credential compromise, phishing, or insider access. This reduces spontaneous exploitation risk compared to unauthenticated SQL injection, but does not eliminate it in environments with weak credential hygiene.

Remediation

Immediate action should focus on: (1) checking CodeAstro's official channels and security advisories for an available patch or update; (2) if no patch exists, applying input validation and parameterized query fixes in-house if source code access is available, or isolating the system from untrusted networks; (3) enforcing strong authentication controls and monitoring administrative account usage; (4) reviewing database access logs for signs of unauthorized queries. Upgrade to a patched version as soon as one becomes available from the vendor.

Patch guidance

Verify the latest security advisory from CodeAstro for available patches to version 1.0. Monitor the vendor's website, support channels, and security bulletins regularly. If a patch is released, apply it immediately to all affected systems during a scheduled maintenance window. Test the patch in a non-production environment first to ensure compatibility with your visitor management workflows. Coordinate with your facility management team to minimize operational disruption.

Detection guidance

Monitor /apartment-visitor/action-visitor.php access logs for suspicious 'remark' parameter values containing SQL keywords (UNION, SELECT, INSERT, DROP, etc.), encoded characters, or unusual string patterns. Enable database query logging and review for abnormal SQL activity, failed authentication attempts against database credentials, or unauthorized schema/table access. Set up alerts on database tables containing visitor records for unexpected modification or deletion operations. Correlate web server and database logs to identify potential attack chains from application logs through to backend queries.

Why prioritize this

Although CVSS 6.3 is rated MEDIUM, this vulnerability merits prompt attention: public disclosure of working exploit code accelerates attacker adoption, authenticated SQL injection can lead to full database compromise, and visitor management systems often contain sensitive personal information protected by data protection regulations. Prioritize patching based on your organization's risk tolerance, regulatory obligations (GDPR, CCPA, etc.), and the sensitivity of visitor data you hold. In high-security or regulated environments, this should be treated as a high-priority remediation.

Risk score, explained

The CVSS 6.3 score (MEDIUM) reflects the authentication requirement (PR:L), which narrows the attack surface. However, the score still accounts for network accessibility (AV:N), low attack complexity (AC:L), and direct impact on confidentiality, integrity, and availability (C:L, I:L, A:L). Organizations should not be reassured by the MEDIUM label given the public disclosure and the critical nature of visitor management data. Context—such as the sensitivity of your data, the strength of your access controls, and regulatory requirements—should inform your internal risk rating.
