CVE-2026-11585 Overview
CVE-2026-11585 is a SQL injection vulnerability in CodeAstro Student Attendance Management System 1.0. The flaw resides in the /attendance-php/Admin/createClassArms.php script, where the classId parameter is passed to a database query without proper sanitization. Authenticated remote attackers can manipulate the parameter to inject arbitrary SQL statements. The exploit has been publicly disclosed, increasing the likelihood of opportunistic abuse against exposed deployments. The weakness is tracked under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).
Critical Impact
Authenticated remote attackers can inject SQL through the classId parameter in createClassArms.php, potentially exposing or modifying student attendance records stored in the backend database.
Affected Products
- CodeAstro Student Attendance Management System 1.0
- Deployments exposing /attendance-php/Admin/createClassArms.php
- Backend MySQL/MariaDB databases linked to the application

Technical Details for CVE-2026-11585
Vulnerability Analysis
The vulnerability stems from improper neutralization of user-supplied input in the administrative createClassArms.php endpoint. The application concatenates the classId request parameter directly into a SQL statement. An attacker with low-privilege authenticated access can send a crafted request that alters the structure of the query. Successful exploitation may read, modify, or delete data within the application's database. The CWE-74 classification reflects the broader class of injection weaknesses where untrusted input flows into a downstream interpreter.
Root Cause
The root cause is the absence of parameterized queries or input validation on the classId argument. The PHP code path responsible for inserting class arm records constructs SQL strings dynamically, trusting client-controlled values. No prepared statements, type casting, or allow-listing mitigate the injection point. This is a common pattern in education-sector PHP applications and aligns with the publicly referenced disclosure on the project's GitHub Issue Tracker.
Attack Vector
The attack vector is network-based and requires authenticated access at a low privilege level. An attacker submits an HTTP request to the createClassArms.php endpoint with a malicious payload supplied through the classId parameter. No user interaction is required beyond the attacker's own session. Because exploitation has been publicly disclosed, automated scanners and opportunistic actors may incorporate the technique. Additional context is available at VulDB CVE-2026-11585.
No verified proof-of-concept code is published. The exploitation mechanism follows the standard SQL injection pattern: appending boolean, UNION, or time-based payloads to the classId value to manipulate the resulting query.
Detection Methods for CVE-2026-11585
Indicators of Compromise
- HTTP requests to /attendance-php/Admin/createClassArms.php containing SQL metacharacters such as single quotes, UNION, SLEEP(, or -- in the classId parameter.
- Database error messages or anomalous query latencies originating from the attendance application's database user.
- Authenticated administrator sessions generating high volumes of requests to class management endpoints.
Detection Strategies
- Inspect web server access logs for classId values that deviate from expected numeric identifiers.
- Enable database query logging and alert on queries against the class arms table that include unusual operators or nested SELECT statements.
- Deploy a web application firewall (WAF) rule set targeting SQL injection signatures on the application's admin path.
Monitoring Recommendations
- Forward web and database logs to a centralized analytics platform and baseline normal createClassArms.php traffic.
- Monitor for privilege changes or schema modifications in the attendance database following suspicious requests.
- Alert on outbound data transfers from the database host that exceed expected operational volumes.
How to Mitigate CVE-2026-11585
Immediate Actions Required
- Restrict access to /attendance-php/Admin/ to trusted administrator IP ranges using network or web server access controls.
- Rotate administrator credentials and review recent admin activity for signs of unauthorized data access.
- Apply input validation at the reverse proxy or WAF layer to reject non-numeric classId values.
Patch Information
No official vendor patch is referenced in the available CVE data. Operators should monitor the CodeAstro Security Resources site and the upstream GitHub Issue Tracker for fix availability. Until a patch is released, code-level remediation requires replacing string concatenation with PHP PDO prepared statements or mysqli_stmt_bind_param for the classId parameter.
Workarounds
- Cast classId to an integer in the application code before it reaches the SQL statement.
- Apply database least-privilege principles so the application account cannot perform schema changes or access unrelated tables.
- Disable or remove the affected endpoint if class arm creation is not actively used in production.
