MindsDB Unrestricted File Upload (CVE-2026-7711) Poses Remote Threat
The National Vulnerability Database (NVD) has detailed CVE-2026-7711, a high-severity vulnerability (CVSS 7.3) affecting MindsDB up to version 26.01. This flaw resides within the exec function of the mindsdb/integrations/handlers/byom_handler/proc_wrapper.py file, specifically within the Engine Handler component.
Attackers can exploit this weakness to achieve unrestricted file upload, opening the door for remote code execution or data manipulation. The NVD notes that the exploit details are publicly available, increasing the urgency for MindsDB users to address this issue. The vendor was reportedly unresponsive to early disclosure attempts.
This vulnerability represents a critical attack surface. An attacker gaining the ability to upload arbitrary files can bypass security controls, introduce malicious payloads, or modify core system functions. For organizations leveraging MindsDB, this isn’t just a theoretical risk – it’s a direct path to compromise if left unpatched.
What This Means For You
- If your organization uses MindsDB, immediately verify your version. Any MindsDB instance up to 26.01 is vulnerable to CVE-2026-7711. Prioritize patching or implementing compensating controls to prevent remote unrestricted file uploads, which can quickly escalate to full system compromise.
