CVE-2026-7711
Published: 04 May 2026
Description
A 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.
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
This control enforces ownership-based restrictions on portable storage device use, directly implementing access control over media insertion into organizational systems.
Hardware write-protect enforces access control on critical resources (e.g., firmware) independent of software state.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Device lock enforces restricted access until re-authentication, directly reducing unauthorized use of active sessions.
Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions.
By automatically labeling outputs with security attributes, the control supports attribute-based enforcement and reduces exploitability of improper access control weaknesses.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Security SummaryAI
CVE-2026-7711 is a vulnerability in MindsDB versions up to 26.01, affecting the exec function within the file mindsdb/integrations/handlers/byom_handler/proc_wrapper.py in the Engine Handler component. The issue enables unrestricted file uploads through remote manipulation, as identified by CWEs-284 (Improper Access Control) and CWE-434 (Unrestricted Upload of File with Dangerous Type). It carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating high severity due to its network accessibility and lack of prerequisites.
Remote attackers require no privileges or user interaction to exploit this vulnerability, allowing them to perform manipulations that result in unrestricted uploads. Successful exploitation grants low-level impacts on confidentiality, integrity, and availability, with a publicly available exploit detailed in a GitHub repository, potentially enabling further attacks such as remote code execution.
Advisories from VulDB and the referenced GitHub proof-of-concept highlight the issue but note no vendor response despite early disclosure contact. No patches or official mitigations are mentioned, leaving affected systems reliant on workarounds like restricting network access to the Engine Handler or upgrading beyond version 26.01 if available.
The exploit's public availability increases the risk of real-world attacks, particularly in environments using MindsDB for data and ML integrations.

MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Unrestricted remote file upload in public-facing MindsDB Engine Handler directly enables T1190 exploitation for initial access; the upload mechanism facilitates T1105 Ingress Tool Transfer of malicious files; exec function in Python proc_wrapper enables T1059.006 arbitrary code execution leading to RCE.
