Databasus Authentication Bypass Enables Account Takeover Via Password Reset Brute Force.

CVE advisorySeverity: CRITICAL (CVSS 9.2)

CVE-2026-110770

The vulnerability exists in an API endpoint used for password resets (/api/v1/users/reset-password). Authentication and password recovery services are typically exposed as public-facing web or API interfaces to allow legitimate users to manage their accounts from any location, making this deployment pattern common for internet-facing applications.

Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability affects the Databasus system, a technology used for database management. It allows attackers to bypass authentication by guessing password reset codes, potentially leading to account takeover, including administrator accounts. The main concern is confirming relevance and exposure within our environment.

Attackers can take over accounts by guessing reset codes.
Unrestricted password resets enable unauthorized access.
Confirm if Databasus is in use and assess impact.

Attack Path

How an attacker could exploit the issue

An attacker can exploit this vulnerability by targeting the password reset feature of the Databasus application. Without needing any prior authentication, they can repeatedly guess the six-digit reset code sent to a user's email. This bypasses security measures like rate limiting or account lockouts, allowing the attacker to gain control of user accounts, including those with administrative privileges.

No authentication required.
Brute-force password reset codes.
Account takeover.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow unauthenticated attackers to bypass authentication and take over user accounts, including administrator accounts, by repeatedly guessing password reset codes without limitations. The affected API endpoint for password reset is exposed externally, making it accessible over the network.

User accounts, including administrators.
Guessing reset codes via POST request.
Unauthorized account access.

Operational Fix

Recommended remediation, mitigation, and detection steps

Platform or infrastructure teams are likely responsible for managing the Databasus application, with support from security teams to address its external-facing API. The first step is to identify all instances of Databasus, confirm their external reachability and business criticality, and then assign an owner for remediation planning.

Identify Databasus instances and exposure.
Verify user account reset functionality.
Plan vendor engagement for remediation.

Frequently asked questions

What is Databasus?

Databasus is a technology designed for database management. It provides administrative features, including user account and authentication services, which allow authorized personnel to manage database environments and system configurations.

What does CVE-2026-110770 mean by authentication bypass?

This vulnerability, classified as CWE-307 (Improper Restriction of Excessive Authentication Attempts), means the password reset mechanism lacks necessary protections. Because the system does not enforce rate limiting or account lockouts, it fails to block automated attempts to guess the six-digit reset code, allowing an attacker to bypass standard identity verification.

How can an attacker trigger this vulnerability?

An attacker initiates the process by requesting a password reset for a known email address via the /api/v1/users/reset-password endpoint. Once triggered, they can repeatedly submit guesses for the six-digit code. Crucially, the vulnerability is not triggered by legitimate user behavior, but rather by the absence of system constraints that would normally invalidate subsequent guesses or block the requester after failed attempts.

Do I need to worry if my Databasus instance is internal?

Halo Surface Signal indicates that because this vulnerability involves an API endpoint typically exposed to allow remote account recovery, internet-facing deployments are at the highest risk. If your instance is purely internal, it is less accessible to external threats, but you should still assess the risk based on the potential impact of an account takeover within your network.

What should I do first to address this CVE?

Start by identifying all deployed instances of Databasus within your infrastructure. Once located, verify their network reachability and determine if they are exposed to the internet. After establishing your inventory and exposure, engage with your platform or security teams to assign ownership for planning remediation steps.
