CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

CVE-2026-86518 is a time-based blind SQL injection vulnerability in the Student CRUD Operation 1.0 application, specifically in the edit.php file. The id parameter used for editing student records is not properly sanitized, allowing attackers to inject malicious SQL code. This can be exploited remotely by sending crafted inputs that cause delays in response times, confirming SQL query execution.

Detection Guidance

To detect this SQL injection vulnerability, test the /edit.php endpoint by injecting time-based payloads into the ID parameter. Use commands like curl to send requests with payloads such as id=(select*from(select(sleep(20)))a). If the server responds with a 20-second delay, the vulnerability is confirmed.

Impact Analysis

This vulnerability could allow unauthorized access to or manipulation of student data in the database. Attackers might extract sensitive information, modify records, or delete data depending on the database permissions. The impact depends on the application's database privileges and the specific SQL queries involved.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection standards like GDPR and HIPAA, which mandate strict controls for protecting sensitive personal data. Unauthorized access or manipulation of student records could result in data breaches, leading to legal penalties, reputational damage, and loss of trust.

Mitigation Strategies

Immediately update the application to use PDO prepared statements with bound parameters for all database queries. Enforce strict server-side validation to ensure the ID parameter is a numeric identifier. Review all CRUD operations for similar vulnerabilities and apply input sanitization.
