Budibase Server SSRF Vulnerability Leaks CouchDB Credentials

Publication date: 2026-08-28

Last updated on: 2026-08-31

Assigner: VulnCheck

Description

Budibase Server before 3.41.3 contains a server-side request forgery vulnerability in the datasource verify endpoint that allows builder-level users to supply arbitrary URLs without SSRF validation. Attackers can exploit this to leak internal CouchDB credentials by making requests to attacker-controlled servers, gaining full database access in cloud deployments.

Attack-Flow Graph

Executive Summary

Budibase Server before version 3.41.3 has a server-side request forgery (SSRF) vulnerability in the datasource verify endpoint. Builder-level users can supply arbitrary URLs without proper SSRF validation. Attackers can exploit this to send requests to internal systems, such as leaking CouchDB credentials, which could grant full database access in cloud deployments.

Detection Guidance

To detect this vulnerability, monitor network traffic for unauthorized requests to internal CouchDB endpoints from builder-level users. Check logs for suspicious SSRF attempts via the datasource verify endpoint in Budibase Server versions before 3.41.3.

Impact Analysis

If you are a Budibase Server user with builder-level access, an attacker could exploit this to access internal systems and steal sensitive data like database credentials. In cloud deployments, this could lead to full database compromise, unauthorized data access, or further network infiltration.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Organizations may face compliance breaches, legal penalties, or reputational damage if exploited.

Mitigation Strategies

Immediately upgrade Budibase Server to version 3.41.3 or later. Restrict builder-level user access to sensitive endpoints and implement strict SSRF validation for all URL inputs in the datasource verify endpoint.
