CVE-2026-9469 Overview
CVE-2026-9469 is a SQL injection vulnerability in the yashpokharna2555 StudentManagementSystem project at commit cb2f558ddf8d19396de0f92abf2d224d46a0a203. The flaw resides in an unspecified function within the /success.php file. Attackers can manipulate the User parameter to inject arbitrary SQL statements into backend queries. The vulnerability is exploitable remotely without authentication or user interaction. A public exploit is available, increasing the likelihood of opportunistic attacks against exposed deployments. Because the project uses a rolling release model, no fixed version is published, and the maintainer has not responded to the issue report disclosed via GitHub. The weakness is classified under CWE-74, Improper Neutralization of Special Elements in Output.
Critical Impact
Unauthenticated remote attackers can inject SQL through the User argument in /success.php, leading to disclosure or modification of database records.

Technical Details for CVE-2026-9469
Vulnerability Analysis
The vulnerability stems from improper neutralization of user-supplied input in the /success.php script. The User request parameter is concatenated into a SQL query without parameterized binding or sanitization. An attacker can submit crafted input containing SQL metacharacters to alter the query structure. This allows extraction of data, authentication bypass, or modification of records depending on the underlying query context.
The exploit has been published, and the project maintainer has not acknowledged the GitHub issue. Because the project distributes via rolling release, defenders cannot pin to a known-good version. Any deployment of StudentManagementSystem exposing /success.php to untrusted networks is at risk.
Root Cause
The root cause is direct concatenation of the User parameter into a SQL statement inside /success.php. The code does not use prepared statements, parameter binding, or input validation. This pattern maps to [CWE-74] and the SQL injection subclass [CWE-89]. Without server-side filtering, any SQL metacharacter sequence reaches the database engine.
Attack Vector
The attack vector is network-based and requires no privileges or user interaction. An attacker issues an HTTP request to /success.php with a malicious User parameter value. Typical payloads include boolean-based conditions, UNION-based extraction, or stacked queries depending on the database driver. The vulnerability mechanism is described in the VulDB Vulnerability #365450 entry and the GitHub Issue #2 Discussion.
No verified exploit code is reproduced here. Refer to the VulDB CTI for #365450 for indicators and exploitation details.
Detection Methods for CVE-2026-9469
Indicators of Compromise
- HTTP requests to /success.php containing SQL metacharacters such as ', --, UNION, SELECT, or OR 1=1 in the User parameter
- Unexpected database errors logged by PHP or the database engine following requests to /success.php
- Outbound database query patterns that include UNION-based extraction or stacked statements originating from the application user
Detection Strategies
- Inspect web server access logs for anomalous User parameter values targeting /success.php
- Deploy a web application firewall rule set that flags SQL injection signatures on PHP endpoints
- Correlate authentication failures and database error responses with the source IP issuing requests to /success.php
Monitoring Recommendations
- Enable verbose query logging on the backend database to capture malformed statements
- Alert on spikes in 500-series responses from /success.php
- Monitor for unauthorized read access to student record tables and credential stores
How to Mitigate CVE-2026-9469
Immediate Actions Required
- Restrict network exposure of /success.php until a code-level fix is applied
- Place the application behind a web application firewall with SQL injection rules enabled
- Audit the /success.php source and replace concatenated queries with parameterized prepared statements
- Rotate any database credentials and review recent query logs for signs of exploitation
Patch Information
No official patch is available. The project follows a rolling release model and has not responded to the disclosure issue. Track the GitHub Repository for Project and the GitHub Issue #2 Discussion for updates. Operators should fork the repository and apply local fixes that convert vulnerable queries to use PDO prepared statements or mysqli_stmt_bind_param.
Workarounds
- Add server-side input validation that rejects non-alphanumeric characters in the User field
- Apply database account least-privilege so the web application cannot read sensitive tables or execute administrative statements
- Block requests to /success.php from untrusted networks via reverse proxy rules until code is remediated
