CVE-2026-7196 Overview
A SQL injection vulnerability has been identified in CodeAstro Online Classroom version 1.0. The vulnerability exists in the /guestdetails file, where manipulation of the deleteid argument enables SQL injection attacks. This flaw allows remote attackers with low privileges to execute arbitrary SQL commands against the underlying database, potentially compromising data confidentiality, integrity, and availability. The exploit has been publicly disclosed and may be actively used.
Critical Impact
Remote SQL injection allowing attackers to manipulate database queries through the deleteid parameter, potentially leading to unauthorized data access, modification, or deletion.

Technical Details for CVE-2026-7196
Vulnerability Analysis
This vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly known as injection. The flaw resides in the /guestdetails endpoint of the CodeAstro Online Classroom application where user-supplied input via the deleteid parameter is not properly sanitized before being incorporated into SQL queries.
The attack can be launched remotely over the network without requiring user interaction, though it does require low-level authentication privileges. The vulnerability affects the confidentiality, integrity, and availability of the application's data, though the impact is limited in scope to the vulnerable component itself.
Root Cause
The root cause stems from improper input validation and lack of parameterized queries in the application's database interaction layer. When processing requests to /guestdetails, the application directly concatenates user-controlled input from the deleteid parameter into SQL statements without proper sanitization or the use of prepared statements. This allows attackers to break out of the intended query structure and inject malicious SQL commands.
Attack Vector
The attack is performed remotely via network access to the vulnerable web application. An authenticated attacker with low privileges can craft malicious HTTP requests containing SQL injection payloads in the deleteid parameter of the /guestdetails endpoint.
The vulnerability allows attackers to manipulate the intended database query to perform unauthorized operations such as extracting sensitive data from the database, modifying or deleting records, or potentially escalating privileges within the application. For technical details regarding exploitation, see the GitHub Issue on VulDB Research and VulDB Vulnerability #359799.
Detection Methods for CVE-2026-7196
Indicators of Compromise
- Unusual SQL error messages in application logs or responses from the /guestdetails endpoint
- HTTP requests to /guestdetails containing suspicious characters in the deleteid parameter such as single quotes, SQL keywords (UNION, SELECT, DROP), or encoded SQL syntax
- Unexpected database query patterns or excessive database errors in logs
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the deleteid parameter
- Monitor application logs for SQL syntax errors or database exceptions originating from the /guestdetails endpoint
- Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
Monitoring Recommendations
- Enable detailed logging for all requests to the /guestdetails endpoint
- Set up alerts for anomalous database query execution times or error rates
- Monitor for unexpected data exfiltration patterns or large result sets from database queries
How to Mitigate CVE-2026-7196
Immediate Actions Required
- Restrict access to the /guestdetails functionality to trusted administrators only until a patch is available
- Implement input validation and whitelist acceptable characters for the deleteid parameter
- Deploy Web Application Firewall rules to filter SQL injection attempts targeting this endpoint
Patch Information
No official patch information is currently available from the vendor. Organizations should monitor the CodeAstro website for security updates and patch releases. In the interim, apply the recommended workarounds and consider disabling the affected functionality if not critical to operations.
Workarounds
- Modify the application code to use parameterized queries or prepared statements for all database interactions involving the deleteid parameter
- Implement strict input validation to ensure the deleteid parameter only accepts expected numeric values
- Consider disabling or restricting access to the /guestdetails endpoint until a permanent fix is implemented
# Example: Restrict access to vulnerable endpoint via web server configuration
# Apache configuration example
<Location /guestdetails>
Require ip 10.0.0.0/8
Require ip 192.168.0.0/16
</Location>
