CVE-2026-14798: SQL Injection in CodeAstro Apartment Visitor Management System 1.0

Technical summary

The vulnerability resides in the /apartment-visitor/visitor-entry.php endpoint, where the 'visname' input parameter is processed unsafely and incorporated into database queries without proper sanitization or parameterized statements. This allows SQL injection (CWE-89) via improper input validation (CWE-74). The attack requires authentication (CVSS vector PR:L) but no user interaction, and is network-accessible. The presence of publicly disclosed exploit code increases the likelihood of opportunistic exploitation.

Business impact

Organizations running CodeAstro Apartment Visitor Management System 1.0 face direct risk to their visitor database integrity and confidentiality. An authenticated employee or contractor with access to the system could extract sensitive resident or visitor information, modify records to grant unauthorized access, or disrupt service availability. For property management firms, this could lead to compliance violations, loss of resident trust, and potential liability if personal data is exposed.

Affected systems

CodeAstro Apartment Visitor Management System version 1.0 is affected. The vulnerability affects the visitor entry processing logic. Organizations should audit their deployment versions and confirm whether they are running version 1.0 or have already upgraded. No vendor product information indicating patches or alternate versions was available in current advisories.

Exploitability

This vulnerability is actively exploitable with low attack complexity. It requires valid authentication credentials but no special user interaction or system configuration. Public exploit code is available, meaning attackers do not need specialized skills to craft attacks. The barrier to exploitation is primarily access to an authenticated account, making insider threats and compromised credentials significant risk vectors.

Remediation

The primary remediation is to upgrade CodeAstro Apartment Visitor Management System to a patched version beyond 1.0, once available from the vendor. Interim mitigation includes applying strict input validation and parameterized prepared statements to all database queries in the affected file, enforcing principle of least privilege on database accounts used by the application, and implementing Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the 'visname' parameter.

Patch guidance

Check the CodeAstro vendor advisory and security portal for available patches. Since version 1.0 is confirmed vulnerable, verify that any upgrade path is to a version explicitly marked as addressing CVE-2026-14798. Apply patches during a maintenance window with appropriate testing in a staging environment first. If no patch is yet available, prioritize the interim mitigations listed above and consider whether operational continuity allows temporary suspension of the visitor entry feature.

Detection guidance

Monitor access logs for /apartment-visitor/visitor-entry.php for unusual POST requests with special characters or SQL keywords in the 'visname' parameter (e.g., quotes, semicolons, UNION, SELECT). Enable database query logging to detect anomalous SQL statements. Use Web Application Firewall or intrusion detection signatures to identify SQL injection attempts. Audit successful logins to accounts that have accessed this endpoint, particularly from unusual IP addresses or at unusual times. Review database access logs for queries originating from the application service account.

Why prioritize this

Although rated MEDIUM severity by CVSS, the combination of public exploit availability, authenticated but low-friction access, and direct database compromise justifies prioritization. Organizations should treat this as HIGH priority for patching or mitigation if the system is internet-facing, stores sensitive personal data, or is accessible by a large number of staff. Organizations with air-gapped or strictly controlled access may rate it lower but should still address it within 30 days.

Risk score, explained

The CVSS 3.1 score of 6.3 reflects network accessibility (AV:N), low attack complexity (AC:L), and authenticated access (PR:L) resulting in confidentiality, integrity, and availability impacts within the affected system boundary. The score does not account for exploit availability or the sensitive nature of visitor/resident data. In practice, the presence of public exploit code and the SQL injection severity may warrant a higher operational risk rating for prioritization purposes.
