CVE-2026-11531
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA security flaw has been discovered in imvks786 student_management_system up to 9599b560ad3c3b83e75d328b76bedcd489ef1f46. This impacts an unknown function of the file admin/admin_login.php of the component Administrator Login Endpoint. Performing a manipulation of the argument a_usr/a_pwd results in sql injection. The attack is possible to be carried out remotely. The exploit has been released to the public and may be used for attacks. This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified. The project was informed of the problem early through an issue report but has not responded yet.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSQL injection vulnerability in the student_management_system admin login page (admin/admin_login.php) allows remote attackers to inject malicious SQL queries through the a_usr and a_pwd parameters, potentially enabling authentication bypass or data exfiltration.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the vulnerable login scriptCheck if the file admin/admin_login.php exists in the web root directory of the imvks786 student_management_systemAffected if The file exists and is accessible via HTTP/HTTPS to the admin login endpoint
-
Inspect SQL query handling for a_usr parameterOpen admin/admin_login.php and search for the a_usr parameter; examine how it is used in database queries - look for direct string concatenation vs prepared statementsAffected if The a_usr value is concatenated directly into SQL queries without using parameterized queries or proper sanitization
-
Inspect SQL query handling for a_pwd parameterOpen admin/admin_login.php and search for the a_pwd parameter; examine how it is used in database queries - look for direct string concatenation vs prepared statementsAffected if The a_pwd value is concatenated directly into SQL queries without using parameterized queries or proper sanitization
-
Verify the authentication mechanism is exposedConfirm that the admin login form at admin/admin_login.php is reachable and accepts user input via POST or GET requestsAffected if The login endpoint is accessible and accepts a_usr and a_pwd parameters without input validation
If the admin/admin_login.php file exists and the a_usr or a_pwd parameters are used in SQL queries without prepared statements or proper sanitization, the environment is vulnerable to CVE-2026-11531.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement prepared statements/parameterized queries for all database operations in the login handler, validate and sanitize user inputs, and consider temporarily disabling the admin login endpoint until a patch is available.
