CVE-2026-10227 Overview
CVE-2026-10227 is a SQL injection vulnerability in the raisulislamg4 student_management_system_by_php project, a PHP-based open-source student management application. The flaw resides in add_user_check.php, part of the User Creation Handler component. Attackers can manipulate the role parameter to inject arbitrary SQL into backend database queries. The issue affects all commits up to 310d950e09013d5133c6b9210aff9444382d16d1. Because the project follows a rolling release model, no specific fixed version is published. The exploit has been disclosed publicly and remote, unauthenticated exploitation is possible over the network.
Critical Impact
Unauthenticated remote attackers can inject SQL into the role parameter of add_user_check.php, potentially exposing or modifying user records stored by the application.

Technical Details for CVE-2026-10227
Vulnerability Analysis
The vulnerability is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component) and manifests specifically as a SQL Injection flaw. The defective code path lives in add_user_check.php, which processes user creation requests submitted to the application. The role parameter is incorporated into a SQL statement without proper parameterization or sanitization. An attacker can submit crafted input through this parameter to alter the structure of the executed query. Because the endpoint is reachable over the network and requires no authentication, exploitation does not depend on prior access. The project maintainer was notified through a GitHub issue but had not responded at the time of disclosure, leaving deployments without an official patch.
Root Cause
The root cause is direct concatenation of user-supplied input from the role HTTP parameter into a SQL query inside add_user_check.php. The User Creation Handler does not apply prepared statements, parameter binding, or input validation before passing the value to the database driver.
Attack Vector
The attack vector is network-based. An attacker sends an HTTP request to the add_user_check.php endpoint with a malicious role value. The injected SQL fragment is executed by the backend database, enabling data extraction, manipulation, or limited tampering with stored credentials and user records.
No verified exploit code is published with the advisory. See the VulDB CVE Report and the GitHub Issue Discussion for additional technical context.
Detection Methods for CVE-2026-10227
Indicators of Compromise
- HTTP POST or GET requests to add_user_check.php containing SQL metacharacters such as single quotes, --, UNION, OR 1=1, or comment sequences in the role parameter.
- Database error messages or stack traces returned from add_user_check.php responses, indicating malformed queries.
- Unexpected new administrative users or modified role assignments in the application user table.
Detection Strategies
- Inspect web server access logs for requests to add_user_check.php where the role argument contains non-alphanumeric content outside the expected role values.
- Deploy web application firewall (WAF) rules that flag SQL injection signatures targeting the role parameter on user creation endpoints.
- Enable database query logging and alert on anomalous queries originating from the application user creation flow.
Monitoring Recommendations
- Correlate HTTP request patterns with downstream database events to detect injection attempts that bypass front-end validation.
- Monitor for repeated failed user creation attempts followed by successful privilege changes, which may indicate exploitation reconnaissance.
- Track outbound database connection volume and query latency for add_user_check.php execution paths.
How to Mitigate CVE-2026-10227
Immediate Actions Required
- Remove add_user_check.php from public network exposure or place the application behind an authenticated reverse proxy until a fix is applied.
- Apply a local code change to use prepared statements with bound parameters for the role value, and validate input against an allow-list of expected role identifiers.
- Review application logs and the user table for evidence of unauthorized account creation or role escalation.
Patch Information
No official patch has been released. The project follows a rolling release model and the maintainer has not responded to the GitHub Issue Discussion reporting the issue. Organizations using this code should fork the repository and apply their own remediation, or migrate to a maintained alternative. Refer to the GitHub Project Repository to track future updates.
Workarounds
- Enforce strict server-side validation on the role parameter, rejecting any value not in a predefined allow-list such as admin, teacher, or student.
- Deploy a WAF rule blocking SQL metacharacters in form submissions to add_user_check.php.
- Restrict the database account used by the application to the minimum privileges required, preventing destructive queries even if injection succeeds.
# Example WAF rule (ModSecurity) to block SQLi attempts on the role parameter
SecRule ARGS:role "@rx (['\";]|--|\b(UNION|SELECT|OR|AND)\b)" \
"id:1010227,phase:2,deny,status:403,msg:'CVE-2026-10227 SQLi attempt on role parameter'"
