CVE-2026-10262: SQL Injection in Real State Services 1.0 Login — CVSS 7.3

Technical summary

CVE-2026-10262 is a SQL injection vulnerability (CWE-89) in the login component of Real State Services 1.0. The affected endpoint /loginuser.php fails to properly sanitize user input in the Username parameter before constructing SQL queries. This improper neutralization of special elements (CWE-74) allows an attacker to break out of the intended SQL context and execute arbitrary database commands. The vulnerability requires no authentication or user interaction and is accessible remotely, making it a network-level attack surface.

Business impact

Successful exploitation could allow attackers to extract sensitive customer data, modify property listings and transaction records, or render the application unusable by deleting critical database entries. For a real estate platform, this threatens confidentiality of client information, integrity of property transactions, and availability of the service. The public disclosure increases the likelihood of exploitation by opportunistic threat actors, elevating risk to customer trust and potential regulatory exposure.

Affected systems

The vulnerability specifically affects code-projects Real State Services version 1.0. Organizations running this software on accessible networks are at risk. The login component is typically one of the first vectors accessed during reconnaissance, making this vulnerability particularly dangerous even before an attacker gains initial access to other systems.

Exploitability

Exploitability is high due to the combination of network accessibility, lack of authentication requirements, and low attack complexity. The vulnerability can be triggered with simple HTTP requests containing SQL metacharacters in the Username field. Public disclosure means proof-of-concept code may already be available or under development. Active exploitation in the wild should be anticipated.

Remediation

Immediate action is required to address this high-severity flaw. Organizations should prioritize identifying systems running Real State Services 1.0, take them offline or isolate them from external networks if an immediate patch is unavailable, and contact the vendor for security updates. As an interim control, implement a Web Application Firewall (WAF) rule to block requests containing common SQL injection patterns in the login form.

Patch guidance

Contact code-projects for available security updates to Real State Services. Verify the patch version against the vendor's official security advisory before deployment. Test patches in a non-production environment first. If no patch is available from the vendor, consider whether the application can be decommissioned or replaced with a more secure alternative.

Detection guidance

Monitor web server logs for unusual patterns in login requests, including requests containing SQL keywords (SELECT, UNION, OR, AND, DROP, etc.) in the Username parameter. Implement database activity monitoring to detect unexpected query patterns or privilege escalation attempts. Check for suspicious authentication failures followed by successful database access. Search for HTTP POST requests to /loginuser.php with URL-encoded SQL syntax in request bodies.

Why prioritize this

This vulnerability scores 7.3 (HIGH) on CVSS 3.1 due to its network accessibility, absence of authentication barriers, and direct impact on data confidentiality, integrity, and availability. The public disclosure and low attack complexity elevate actual risk beyond the base score. Real estate platforms are attractive targets for data theft and fraud. Patching should begin immediately.

Risk score, explained

The CVSS 3.1 score of 7.3 reflects: Attack Vector Network (AV:N) — remotely exploitable; Attack Complexity Low (AC:L) — no special conditions required; Privileges Required None (PR:N) — no authentication needed; User Interaction None (UI:N) — exploitation requires no victim action; Confidentiality, Integrity, and Availability all impacted at Low level (C:L/I:L/A:L). This score appropriately captures the threat, though the public disclosure and real-world exploitability trend suggest practical risk may exceed the baseline assessment.
