Unauthenticated SSRF in CloudBeaver Connection Testing

Moderate
mayerro published GHSA-8wwr-2cv6-q65q Sep 25, 2026

Package

cloudbeaver

Affected versions

<= 26.1.2

Patched versions

26.1.3

Description

Summary

CloudBeaver before 26.1.3 allowed unauthenticated users to initiate connection checks using attacker-controlled connection parameters. This could cause the CloudBeaver server to make outbound network requests to arbitrary hosts, resulting in a server-side request forgery vulnerability.

Impact

An unauthenticated remote attacker could interact with internal network services reachable from the CloudBeaver server. Depending on the deployment environment and enabled drivers, this could allow internal service discovery, network probing, or access to cloud instance metadata endpoints.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Missing Authentication for Critical Function

The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources. Learn more on MITRE.

Server-Side Request Forgery (SSRF)

The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. Learn more on MITRE.
