CVE-2026-7092: Invoice System Laravel Auth Bypass Flaw

CVE-2026-7092 Overview

A vulnerability has been identified in code-projects Invoice System in Laravel 1.0 that allows improper authorization through the Profile Handler component. The vulnerability affects an unknown function of the file /profile/ where manipulation of the argument ID leads to improper authorization. This flaw can be exploited remotely by authenticated attackers.

Critical Impact
Authenticated attackers can exploit improper authorization controls to access or modify profile data belonging to other users by manipulating the ID parameter, potentially leading to unauthorized data access and privilege abuse.

Affected Products

code-projects Invoice System in Laravel 1.0
Profile Handler component (/profile/ endpoint)
Systems with inadequate authorization controls on profile ID parameters

Technical Details for CVE-2026-7092

Vulnerability Analysis

This vulnerability is classified as CWE-266 (Incorrect Privilege Assignment), which occurs when the application fails to properly verify that users are authorized to access the resources they request. In this case, the Profile Handler component does not adequately validate whether the authenticated user has permission to access or modify the profile associated with the provided ID parameter.

The vulnerability exists in the /profile/ endpoint where the application accepts an ID argument to identify which profile to retrieve or modify. Due to insufficient authorization checks, an attacker can manipulate this ID value to access profiles belonging to other users, effectively bypassing the intended access control mechanisms.

Root Cause

The root cause of this vulnerability stems from inadequate server-side authorization validation. The application appears to trust client-supplied ID parameters without verifying that the authenticated user has permission to access the requested profile. This is a common pattern in Insecure Direct Object Reference (IDOR) vulnerabilities where user-controlled input directly references internal objects.

The Profile Handler component fails to implement proper access control checks that would compare the requested profile ID against the authenticated user's session or permissions, allowing any authenticated user to potentially access any profile by modifying the ID parameter.

Attack Vector

The attack can be executed remotely over the network by authenticated users. An attacker would:

Authenticate to the Invoice System application with valid credentials
Navigate to the /profile/ endpoint with their own profile ID
Manipulate the ID parameter in the request to reference another user's profile
Access or modify sensitive profile information belonging to other users

The vulnerability exploitation mechanism involves manipulating the ID parameter in requests to the /profile/ endpoint. An attacker with low-level privileges can iterate through profile IDs or use predictable ID patterns to enumerate and access other users' profile data. Technical details and proof-of-concept information are available through the GitHub Gist Script and VulDB Vulnerability #359667.

Detection Methods for CVE-2026-7092

Indicators of Compromise

Unusual access patterns to /profile/ endpoints with sequential or enumerated ID values
Multiple profile access requests from a single authenticated session with different ID parameters
Access logs showing users retrieving profiles that don't match their session identity
Failed or successful profile modifications for profiles not owned by the requesting user

Detection Strategies

Implement application-level logging to track profile access patterns and flag requests where the accessed profile ID differs from the authenticated user's profile
Deploy web application firewalls (WAF) with rules to detect parameter manipulation and IDOR attack patterns
Configure intrusion detection systems to alert on anomalous API request patterns to the /profile/ endpoint
Use behavioral analytics to identify users accessing multiple profiles in rapid succession

Monitoring Recommendations

Enable detailed access logging for all Profile Handler endpoints with user session correlation
Monitor for automated scanning tools or scripts targeting the profile endpoint with enumerated IDs
Implement real-time alerting for authorization failures or access control violations
Review application logs regularly for evidence of profile enumeration attempts

How to Mitigate CVE-2026-7092

Immediate Actions Required

Implement server-side authorization checks to verify the authenticated user owns or has permission to access the requested profile
Add session-based validation that compares the requested profile ID against the authenticated user's permissions
Consider removing direct ID references from URLs in favor of session-based profile access
Review and audit all endpoints that accept user-controlled identifiers for similar authorization flaws

Patch Information

No official vendor patch has been identified at this time. Organizations using code-projects Invoice System in Laravel 1.0 should implement the workarounds described below and monitor for security updates from Code Projects. Additional vulnerability details can be found at VulDB Submission #800388.

Workarounds

Implement custom middleware to validate authorization before processing profile requests
Add access control logic that restricts profile access to only the profile owner or administrators
Use Laravel's built-in authorization policies and gates to enforce proper access controls
Consider implementing UUID-based profile identifiers instead of sequential numeric IDs to reduce enumeration risk

bash

# Example Laravel authorization check (conceptual)
# Add to your ProfileController to enforce authorization
# Note: Adapt this to your specific implementation

# In app/Http/Controllers/ProfileController.php
# Add authorization check before processing profile requests:
# if ($request->user()->id !== $profileId && !$request->user()->isAdmin()) {
#     abort(403, 'Unauthorized access to profile');
# }

# Consider using Laravel's Gate facade:
# Gate::define('view-profile', function ($user, $profile) {
#     return $user->id === $profile->user_id;
# });
