Executive Summary

CVE-2026-86277 is an authorization bypass vulnerability in the Syllabus-Aligned Learning Management & Examination System 1.0. It involves Insecure Direct Object Reference (IDOR) flaws in multiple PHP files, allowing unauthorized access and modification of data due to missing ownership verification checks. Attackers can manipulate parameters like 'id' to bypass authorization and perform actions beyond their permissions.

Detection Guidance

To detect this vulnerability, inspect the affected PHP files (delete_exam.php, approve_enrollment.php, download.php, edit_exam.php, take_exam.php, view.php) for missing authorization checks. Check if user-controlled parameters like 'id' or 'status' are used without verifying ownership or permissions. Test by manipulating these parameters to see if unauthorized actions are possible.

Impact Analysis

This vulnerability allows attackers to delete exams, manipulate enrollment statuses, access unauthorized content, edit exams, take exams without enrollment, and download files without proper authentication. It can lead to data loss, integrity compromise, unauthorized access, and exam fraud. The impact includes both read and write operations depending on the affected file.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection and access control. It enables unauthorized access to sensitive data (e.g., exams, enrollments), which could result in breaches of confidentiality under GDPR and HIPAA. Organizations using this system may face legal penalties for failing to protect personal and sensitive information.

Mitigation Strategies

Immediately add ownership verification checks before state-changing operations in all affected files. Validate user-controlled parameters against allowlists and enforce proper authorization checks. Ensure only authenticated users with correct permissions can access or modify data. Review and restrict access to the 'uploads/syllabus/' directory.
