Lara Dashboard Authentication Bypass via Screenshot Login Route.

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2026-86184

Lara Dashboard is a web application framework. The vulnerable route is part of the application's authentication and management interface. Such web-based administration dashboards are commonly deployed as internet-facing services to allow remote access for administrators, making them reachable from the public internet in typical deployment patterns.

Missing Authentication

Horizon Alert

Summary of the vulnerability and why it matters

A vulnerability in the Lara Dashboard's login feature allows unauthorized access to user accounts and system functions, including code execution, when certain environmental settings are not production. This could expose sensitive data and system controls.

Bypass authentication for any user by email.
Affects administrative dashboards, common for remote access.
Confirm relevance and ensure proper environment configuration.

Attack Path

How an attacker could exploit the issue

An attacker could bypass authentication to access Lara Dashboard if the application environment is not set to production. By sending a request to a specific endpoint with a registered user's email, an unauthenticated attacker can gain full access as that user. This allows them to view sensitive information, change settings, and potentially execute arbitrary code.

No prior authentication required.
Request specific email login endpoint.
Unauthorized user access and code execution.

Live Threat

Current exploitation, exposure, and threat context

When the application environment is not set to production, this vulnerability could allow an unauthenticated attacker to bypass authentication and access any user's account. This could lead to unauthorized access to user administration, settings, database contents, and potentially arbitrary code execution.

User account access and sensitive system data.
Attacker requests a specific endpoint with a registered email.
Unauthorized access and arbitrary code execution.

Operational Fix

Recommended remediation, mitigation, and detection steps

Application owners and platform teams are likely responsible for addressing this authentication bypass vulnerability. The initial step should be to discover all instances of Lara Dashboard within the environment, confirm their reachability and criticality, and then identify the accountable owner for remediation planning.

Identify application owners for all deployments.
Verify reachability and business criticality.
Plan remediation based on risk assessment.

Frequently asked questions

What is Lara Dashboard?

Lara Dashboard is a web application framework designed to provide administrative interfaces for managing data and system settings. It is often used by developers to build back-end management portals that allow administrators to perform tasks like user management, database operations, and module configuration via a graphical user interface.

What does CWE-306 mean for CVE-2026-86184?

CWE-306 refers to a Missing Authentication for Critical Function weakness. In the context of CVE-2026-86184, this means a specific part of the software, designed to be protected, fails to verify the identity of the person accessing it. Because the screenshot-login route lacks this essential check, an attacker can interact with sensitive administrative features as if they were a legitimate user without providing any credentials.

How does an attacker trigger this vulnerability?

An attacker can bypass authentication by sending a simple web request to a specific URL endpoint that includes a registered user's email address. Crucially, this vulnerability only triggers when the software's environment is not configured as 'production.' If the application is correctly set to the production environment, this specific bypass route is not active and cannot be exploited in the same way.

Is my Lara Dashboard instance at risk?

Halo Surface Signal notes that Lara Dashboard is frequently deployed as an internet-facing service for remote administrative access. If your installation is reachable from the public internet and is not configured to run in a production environment, it is exposed to this risk. You should review your network perimeter and environment configurations to see if the interface is accessible to unauthorized parties.

What are the first steps to address this CVE?

Begin by locating all deployed instances of Lara Dashboard within your infrastructure and confirming which ones are currently running in non-production environments. Once identified, prioritize updating to version 1.3.0 or higher, which resolves the vulnerability. Additionally, ensure that your application environment settings are strictly configured to production to provide an extra layer of defense.
