CVE-2026-27483 Scanner

MindsDB is an AI-powered database used by data analysts, machine learning engineers, and other tech professionals to make data science projects more accessible and faster to deploy. By facilitating the integration and deployment of AI models, it helps users automate decision-making processes directly in their databases. Organizations and developers leverage MindsDB's capabilities to build predictive models, thereby enhancing their existing applications with advanced analytics features. It finds application in sectors such as finance, healthcare, marketing, and any domain where data-driven insights are crucial. MindsDB allows users to query both data and models as if they were simple SQL databases, making it especially useful for bridging the gap between data science and traditional database management. Its API and integrations make it adaptable to various infrastructures and workflows, aiding the growth of data-driven transformations.

The vulnerability in question, Remote Code Execution (RCE), allows attackers to execute arbitrary commands on the server hosting MindsDB. This type of vulnerability poses a significant risk as it gives unauthorized users the ability to run malicious software that can affect the system's integrity and confidentiality. The RCE in MindsDB arises from inadequate input validation, particularly in the file upload module. This permits authenticated attackers to exploit path traversal vulnerabilities to deploy unauthorized files and execute them as part of the server's operations. RCE vulnerabilities are notorious for being exploited in building botnets, launching ransomware attacks, or exfiltrating sensitive data from the compromised server. Thus, they require prompt attention and remediation to secure any exposed software environments.

Technical details reveal that the vulnerability resides in the /api/files endpoint of MindsDB's HTTP interface. Authenticated users can exploit this by crafting a specially designed request that traverses file paths, hence bypassing the intended access controls. This involves tampering with the file parameter in HTTP requests to write files in system directories unintended by the application's original design, thereby opening up avenues for command execution. As part of the exploit, crafted files can invoke system commands or install malicious payloads using the server's authority. Moreover, this potentially allows attackers to modify configurations, tamper with data, or gain further escalated access to the server environment. The described vulnerability is crucial as it exists prior to version 25.9.1.1 of MindsDB.

If this vulnerability is exploited, it could lead to various detrimental outcomes including unauthorized access to data, disruption of service, defacement, unauthorized resource usage, and potential loss of reputation. Compromised systems could be used as vectors to launch additional attacks or be coerced into illegal activities at the attackers' behest. Moreover, such a breach might result in an obligatory public disclosure, legal consequences, and financial penalties for the entity using the vulnerable software. The possibility of remote command execution grants attackers virtually unlimited control over the compromised hosts, making it vital to assess and mitigate this risk.
