CVE-2026-7711
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA weakness has been identified in MindsDB up to 26.01. This impacts the function exec of the file mindsdb/integrations/handlers/byom_handler/proc_wrapper.py of the component Engine Handler. Executing a manipulation can lead to unrestricted upload. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceMindsDB's BYOM (Bring Your Own Model) handler contains an unrestricted upload vulnerability in the exec function within mindsdb/integrations/handlers/byom_handler/proc_wrapper.py. The exec function lacks proper input validation, allowing remote attackers to upload arbitrary files to the system by manipulating the function's execution. This is a remote attack vector with publicly available exploits.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm MindsDB installationRun 'pip show mindsdb' or check your package manager to identify if MindsDB is installed and retrieve the version numberAffected if MindsDB is installed and the version falls within the affected range (if known)
-
Verify BYOM handler presenceCheck for the existence of mindsdb/integrations/handlers/byom_handler/ directory and the proc_wrapper.py file within your MindsDB installationAffected if The BYOM handler and proc_wrapper.py file exist in the installation
-
Inspect the vulnerable exec usageExamine the proc_wrapper.py file in the BYOM handler for unrestricted exec function calls without input validation on the code parameterAffected if The file contains exec() calls that accept user-controlled input without sanitization
-
Check BYOM handler configurationLook at the BYOM handler configuration or startup settings to determine if the handler is enabled and accessibleAffected if The BYOM handler is enabled and accessible to users or external connections
-
Review network exposureDetermine if the MindsDB server is exposed to network access and whether authentication is required for BYOM functionalityAffected if The BYOM endpoint is accessible remotely without proper authentication controls
Your environment is affected if MindsDB with the BYOM handler is installed, the vulnerable exec-based code in proc_wrapper.py exists without input validation, and the handler is accessible (with or without authentication) to potential attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation and authorization controls on the exec function in proc_wrapper.py. Restrict file upload operations to permitted paths and file types, and add authentication checks before allowing execution. Consider using parameterized calls instead of direct exec invocations.
