DescriptionGitHub Advisory

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.

AnalysisAI

Remote code execution in MindsDB prior to version 25.9.1.1 allows authenticated attackers to bypass file upload restrictions through path traversal in the /api/files endpoint. An attacker can exploit insufficient filename validation to write arbitrary files to any location on the server, achieving command execution. Public exploit code exists for this vulnerability.
