Unauthenticated Remote Code Execution in MindsDB Minds Platform

Publication date: 2026-08-14

Last updated on: 2026-08-14

Assigner: VulnCheck

Description
MindsDB Minds Platform version 26.1.0 and earlier contains an unauthenticated remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary OS commands by submitting crafted prompts to the unprotected POST /api/v1/responses/ endpoint, which reaches the Anton agent's scratchpad tool that calls exec() on attacker-influenced Python source without sandboxing. Attackers can first configure their own LLM API key through the unauthenticated PUT /api/v1/settings/ endpoint, then POST a prompt directing the agent to invoke the scratchpad tool with arbitrary Python code, achieving full OS command execution as the user running the desktop application and enabling access to SSH keys, stored credentials, and environment secrets.

Executive Summary

CVE-2026-73678 is a critical unauthenticated remote code execution (RCE) vulnerability in MindsDB Minds Platform versions 26.1.0 and earlier. It allows attackers to execute arbitrary OS commands without authentication by sending crafted prompts to the POST /api/v1/responses/ endpoint. The vulnerability stems from three flaws: no authentication on the API, permissive CORS configuration, and unrestricted use of exec() in the Anton agent's scratchpad tool. Attackers can configure their own LLM API key via the unauthenticated PUT /api/v1/settings/ endpoint and then submit a prompt to execute arbitrary Python code, achieving full OS command execution as the user running the application.

This enables access to sensitive data like SSH keys, stored credentials, and environment secrets. The vulnerability has a CVSS score of 10.0, indicating maximum severity.

Detection Guidance

Check if your MindsDB Minds Platform version is 26.1.0 or earlier. Inspect network traffic for POST requests to /api/v1/responses/ or PUT requests to /api/v1/settings/ without authentication. Monitor for unexpected Python code execution or system commands.

Impact Analysis

This vulnerability can lead to full system compromise. Attackers can execute arbitrary OS commands, steal credentials, access sensitive data, destroy data, or establish persistence mechanisms. The attack can be triggered by a victim simply visiting a malicious webpage, making it a drive-by exploitation scenario. Since no authentication is required, any user running the affected application is at risk.

Compliance Impact

This vulnerability likely violates compliance requirements for GDPR and HIPAA due to unauthorized access to sensitive data, including credentials and environment secrets. GDPR requires protection of personal data, while HIPAA mandates safeguards for protected health information. The ability to execute arbitrary code and access sensitive data without authentication would result in non-compliance with these standards.

Mitigation Strategies

Upgrade MindsDB Minds Platform to a version beyond 26.1.0 immediately. Disable unauthenticated access to /api/v1/responses/ and /api/v1/settings/ endpoints. Implement strict CORS policies and disable the scratchpad tool's exec() function. Block external access to these endpoints if possible.
