CVE-2026-14796: SQL Injection in CodeAstro Apartment Visitor Management System 1.0

Technical summary

CVE-2026-14796 is a remote SQL injection vulnerability stemming from insufficient input validation on the 'fromdate' parameter within report.php. The vulnerability chain involves improper neutralization of special elements used in an SQL command (CWE-89) combined with neutral execution (CWE-74), allowing authenticated users to bypass security controls and execute arbitrary SQL queries. The CVSS 3.1 score of 6.3 reflects the requirement for authentication (PR:L) but acknowledges the direct impact to confidentiality, integrity, and availability (C:L/I:L/A:L) without user interaction needed (UI:N).

Business impact

Organizations deploying CodeAstro's Apartment Visitor Management System face exposure of visitor records, lease information, and operational data stored in the application database. An insider threat or compromised user account could be leveraged to extract or modify sensitive tenant and guest information. Additionally, attackers could corrupt data or degrade system availability, disrupting building management operations and potentially violating tenant privacy obligations.

Affected systems

CodeAstro Apartment Visitor Management System version 1.0 is confirmed vulnerable. Verify whether your organization has deployed this specific version or whether later versions have addressed this flaw by reviewing CodeAstro's security advisories and patch releases.

Exploitability

The vulnerability is remotely exploitable by any authenticated user of the system, meaning attackers with valid credentials—obtained through phishing, credential stuffing, or employee compromise—can conduct attacks without special privileges or user interaction. Public availability of exploit code significantly lowers the barrier to exploitation and increases the likelihood of opportunistic attacks.

Remediation

Immediately assess whether your environment uses CodeAstro Apartment Visitor Management System 1.0. If deployed, prioritize upgrading to a patched version released by CodeAstro. In parallel, implement network segmentation to restrict access to the application, enforce strong authentication policies, and monitor application logs for suspicious SQL patterns in report parameters. Consider deploying a Web Application Firewall (WAF) configured with SQL injection detection rules as a temporary measure pending patching.

Patch guidance

Contact CodeAstro directly to identify available patches for version 1.0. Verify the patch version number against CodeAstro's official security bulletin before applying. If no official patch exists, escalate to CodeAstro for an expected timeline or workaround guidance. Test any patch in a non-production environment before rollout.

Detection guidance

Monitor application access logs for authentication events followed by report.php requests containing SQL metacharacters (single quotes, semicolons, UNION keywords, etc.) in the fromdate parameter. Query your database activity logs for unusual SQL commands originating from the application user account. Implement alerting on failed SQL queries, error messages containing SQL syntax, or unusual query execution patterns during the reporting feature's normal operation window.

Why prioritize this

Although this vulnerability carries a MEDIUM CVSS score, the combination of public exploit availability, authenticated-user requirement matching insider-threat scenarios, and direct database access warrants rapid patching. The data exposure risk to visitor and tenant information elevates business concern beyond the numeric risk score alone.

Risk score, explained

The CVSS 3.1 score of 6.3 reflects the authentication prerequisite (lowering severity) balanced against the direct impact to data confidentiality, integrity, and availability. The network-accessible vector (AV:N/AC:L) and lack of user interaction required (UI:N) indicate ease of exploitation. Public exploit availability transforms this from a theoretical vulnerability into an active threat requiring urgent attention despite the MEDIUM classification.
