CVE-2026-27483: MindsDB has Path Traversal in /api/files Leading to Remote Code Execution

Noroxi assessment

Priority: Monitor (action score 38/100)

A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
Public proof-of-concept code exists (Exploit-DB, GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 10.9% (FIRST EPSS); higher than 95.8% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: mindsdb (PyPI) 25.9.1.1.

Low priority for now. Upgrade to mindsdb (PyPI) 25.9.1.1 or later.

MindsDB is a platform for building artificial intelligence from enterprise data. Prior to version 25.9.1.1, there is a path traversal vulnerability in Mindsdb's /api/files interface, which an authenticated attacker can exploit to achieve remote command execution. The vulnerability exists in the "Upload File" module, which corresponds to the API endpoint /api/files. Since the multipart file upload does not perform security checks on the uploaded file path, an attacker can perform path traversal by using `../` sequences in the filename field. The file write operation occurs before calling clear_filename and save_file, meaning there is no filtering of filenames or file types, allowing arbitrary content to be written to any path on the server. Version 25.9.1.1 patches the issue.
