CVE-2026-14743 Overview
CVE-2026-14743 is a SQL injection vulnerability in code-projects Real State Services 1.0. The flaw resides in an unspecified function within the /normalHomeSale.php file. Attackers can manipulate the loc parameter to inject arbitrary SQL statements into the backend database query. The vulnerability is exploitable remotely over the network and requires no authentication or user interaction. A public exploit has been referenced through VulDB and a GitHub issue tracker, increasing the likelihood of opportunistic exploitation against exposed installations.
Critical Impact
Unauthenticated remote attackers can inject SQL commands through the loc parameter of /normalHomeSale.php, potentially exposing or altering data in the application database.
Affected Products
- code-projects Real State Services 1.0
- Vulnerable file: /normalHomeSale.php
- Vulnerable parameter: loc

Technical Details for CVE-2026-14743
Vulnerability Analysis
The vulnerability is classified under [CWE-74] as improper neutralization of special elements in output used by a downstream component (Injection). The loc parameter passed to /normalHomeSale.php is concatenated into a SQL statement without adequate sanitization or parameterization. Attackers can inject payloads such as UNION SELECT statements, boolean-based conditions, or time-based delays to extract data or manipulate query logic.
Exploitation does not require credentials, and the attack can be delivered through any HTTP client. The publicly referenced proof-of-concept demonstrates weaponization is straightforward for actors with basic knowledge of SQL injection techniques.
Root Cause
The root cause is the direct inclusion of user-controlled input from the loc request parameter into a SQL query string. The application fails to use prepared statements, parameterized queries, or input validation routines. Any characters supplied by the client become part of the executed database command.
Attack Vector
The attack originates from the network. An adversary sends a crafted HTTP request to /normalHomeSale.php with a malicious loc value. Because no authentication is required, exposed instances of Real State Services 1.0 are reachable by any remote attacker. Successful exploitation yields limited confidentiality, integrity, and availability impact on the underlying database.

Detection Methods for CVE-2026-14743
Indicators of Compromise
- HTTP requests to /normalHomeSale.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the loc parameter.
- Web server access logs showing anomalous or oversized loc parameter values from external IP addresses.
- Database error messages returned in HTTP responses indicating malformed queries originating from the normalHomeSale.php endpoint.
Detection Strategies
- Deploy web application firewall (WAF) rules that inspect the loc parameter for SQL injection patterns.
- Enable database query auditing to flag unusual query structures referencing tables outside the normal application workflow.
- Correlate HTTP request logs with database errors to identify probing activity against the vulnerable endpoint.
Monitoring Recommendations
- Alert on high-frequency requests to /normalHomeSale.php from a single source, which may indicate automated exploitation attempts.
- Monitor outbound database connections for unexpected data exfiltration volumes following requests to the affected endpoint.
- Track authentication logs and application error logs for anomalies that follow injection attempts.
How to Mitigate CVE-2026-14743
Immediate Actions Required
- Restrict network access to the Real State Services application until a fix is available, using firewall rules or IP allowlists.
- Deploy WAF signatures that block SQL injection payloads targeting the loc parameter of /normalHomeSale.php.
- Review database and web server logs for evidence of prior exploitation attempts.
Patch Information
No official vendor patch has been published in the referenced advisories at the time of this writing. Administrators should monitor the Code Projects website and the VulDB Vulnerability #376329 entry for updates.
Workarounds
- Modify the application source to use parameterized queries or prepared statements for all database interactions involving the loc parameter.
- Apply strict server-side input validation to reject non-alphanumeric characters in location values.
- Enforce least-privilege database credentials so the web application account cannot read or modify data outside its required scope.
