CVE-2026-26891: Logistic Hub Parcel System SQLi Flaw

CVE-2026-26891 Overview

A SQL Injection vulnerability has been identified in Sourcecodester Logistic Hub Parcel's Management System v1.0. The vulnerability exists in the /manage_parcel_type.php endpoint, allowing authenticated attackers with high privileges to inject malicious SQL queries through improperly sanitized input parameters. This flaw enables unauthorized access to sensitive database information.

Critical Impact

Authenticated attackers with administrative privileges can exploit this SQL Injection vulnerability to extract confidential data from the application's database, potentially compromising customer information, parcel tracking data, and system credentials.

Affected Products

• Sourcecodester Simple Logistic Hub Parcel's Management System v1.0
• oretnom23 simple_logistic_hub_parcel's_management_system 1.0

Technical Details for CVE-2026-26891

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) affects the /manage_parcel_type.php file in the Sourcecodester Logistic Hub Parcel's Management System. The application fails to properly sanitize user-supplied input before incorporating it into SQL queries, creating an injection point that can be exploited by authenticated users with administrative access.

The vulnerability requires network access and high-level privileges to exploit, limiting the attack surface to authenticated administrators. However, once exploited, it allows direct interaction with the backend database, enabling data extraction operations. The impact is primarily confidentiality-focused, allowing attackers to read sensitive information stored in the database.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries or prepared statements in the manage_parcel_type.php file. User-supplied input is directly concatenated into SQL query strings without proper sanitization, escaping, or the use of safe database APIs. This classic SQL Injection pattern allows attackers to manipulate query logic and extract unauthorized data.

Attack Vector

The attack is executed over the network against the web application's /manage_parcel_type.php endpoint. An attacker with administrative credentials can craft malicious input containing SQL syntax that alters the intended query behavior. When the application processes this input, the injected SQL commands are executed against the database.

The vulnerability manifests when user-controlled parameters are processed by the parcel type management functionality. By injecting SQL statements such as UNION-based queries or time-based blind injection payloads, an attacker can enumerate database structure, extract table contents, and access confidential data. Technical details and proof-of-concept information can be found in the GitHub SQL Injection Report.

Detection Methods for CVE-2026-26891

Indicators of Compromise

• Unusual SQL error messages in web server logs related to /manage_parcel_type.php
• HTTP requests to /manage_parcel_type.php containing SQL keywords such as UNION, SELECT, OR 1=1, or encoded SQL syntax
• Abnormal database query patterns or increased query execution times from web application connections
• Unexpected data access patterns or bulk data retrieval from administrative accounts

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL Injection patterns targeting /manage_parcel_type.php
• Enable SQL query logging on the database server and monitor for anomalous query structures
• Deploy application-level security monitoring to detect input containing SQL meta-characters
• Configure intrusion detection systems (IDS) with signatures for common SQL Injection payloads

Monitoring Recommendations

• Monitor web server access logs for repeated requests to /manage_parcel_type.php with unusual parameter values
• Set up alerts for database errors indicating SQL syntax issues from the web application
• Track administrative user sessions for unusual activity patterns or data access behaviors
• Review authentication logs for compromised or suspicious administrative account usage

How to Mitigate CVE-2026-26891

Immediate Actions Required

• Restrict access to the /manage_parcel_type.php endpoint to only essential administrative users
• Implement Web Application Firewall rules to block SQL Injection attempts
• Review and audit all administrative account credentials for potential compromise
• Consider taking the application offline if highly sensitive data is at risk until a patch is applied

Patch Information

As of the last modification date (2026-03-04), no official vendor patch has been released for this vulnerability. Organizations using this software should monitor the vendor's repository for security updates. Given that this is an open-source project from Sourcecodester, users may need to apply manual code fixes or implement compensating controls until an official patch becomes available.

The recommended remediation approach involves modifying the vulnerable code to use prepared statements or parameterized queries instead of string concatenation for SQL query construction.

Workarounds

• Implement input validation to reject parameters containing SQL keywords and special characters
• Use a Web Application Firewall (WAF) with SQL Injection protection rules enabled
• Apply the principle of least privilege by limiting database user permissions for the web application
• Consider implementing database query whitelisting or stored procedures to limit executable SQL operations
