CVE-2024-45849·Python vulnerability

An arbitrary code execution vulnerability exists in versions 23.10.5.0 up to 24.7.4.1 of the MindsDB platform, when the Microsoft SharePoint integration is installed on the server. For databases created with the SharePoint engine, an ‘INSERT’ query can be used for list creation. If such a query is specially crafted to contain Python code and is run against the database, the code will be passed to an eval function and executed on the server.

How to fix this CVE

Update MindsDB to version 24.7.4.1 or later immediately if you have the Microsoft SharePoint integration enabled. This vulnerability allows arbitrary Python code execution through specially crafted INSERT queries against SharePoint-backed databases. Patch your installation and review access logs for signs of exploitation targeting the SharePoint engine.

sudo dnf update python3

Defensia detects this vulnerability

WAF mitigation (if patching is not yet possible)

Add this rule to your WAF to block exploitation attempts while you schedule the patch. 

Implement input validation on database INSERT statements to block embedded Python code patterns. Block or sanitize common eval() function markers such as '__import__', 'exec(', 'compile(', and '__builtins__' when processing SharePoint database queries. Restrict database user privileges to minimum necessary access and enforce query whitelisting for production environments.

How to check if you are affected

  1. Step 1: Check MindsDB version with 'mindsdb --version' or by querying the MindsDB system tables using a SQL client
  2. Step 2: Confirm if SharePoint integration is installed by listing enabled engines in MindsDB configuration file at /etc/mindsdb/config.json or checking the MindsDB Studio UI for active integrations
  3. Step 3: Search MindsDB query logs for INSERT statements targeting SharePoint engine databases; look for patterns like 'INSERT INTO <sharepoint_db>.*list.*' in logs at ~/.mindsdb/logs/
  4. Step 4: Verify the fix by re-running 'mindsdb --version' after upgrade and confirm it reports version 24.7.4.1 or later

FAQ

What is CVE-2024-45849?

CVE-2024-45849 is an arbitrary code execution vulnerability in MindsDB versions 23.10.5.0 through 24.7.4.0 that allows attackers with database access to execute malicious Python code by embedding it in INSERT queries targeting SharePoint-connected databases.

Is CVE-2024-45849 being actively exploited?

No, this vulnerability is not currently listed on the CISA KEV catalog and no public exploits are available, though the attack surface is limited to authenticated users with database access.

What versions of MindsDB are affected by CVE-2024-45849?

MindsDB versions 23.10.5.0 through 24.7.4.0 are vulnerable when the Microsoft SharePoint integration is installed. Version 24.7.4.1 and later are patched.

How do I check if my server is vulnerable to CVE-2024-45849?

Run 'mindsdb --version' to check the MindsDB version, then verify if SharePoint integration is enabled by examining the MindsDB configuration and active engines. If both conditions are met and the version is below 24.7.4.1, your system is vulnerable.

Does Defensia detect CVE-2024-45849?

Yes — Defensia's CVE advisory scanner compares installed MindsDB package versions against the NVD database. If MindsDB is installed on a monitored server, CVE-2024-45849 will appear in your dashboard with remediation steps.

CVE-2026-33054CVSS 10Mesop is a Python-based UI framework that allows users to build web applications. Versions 1.2.2 and below contain a Path Traversal vulnerability that allows any user supplying an untrusted state_token through the UI stream payload to arbitrarily target files on the disk under the standard file-based runtime backend. This can result in application denial of service (via crash loops when reading non-msgpack target files as configurations), or arbitrary file manipulation. This vulnerability heavily exposes systems hosted utilizing FileStateSessionBackend. Unauthorized malicious actors could interact with arbitrary payloads overwriting or explicitly removing underlying service resources natively outside the application bounds. This issue has been fixed in version 1.2.3.
CVE-2026-34938CVSS 10PraisonAI is a multi-agent teams system. Prior to version 1.5.90, execute_code() in praisonai-agents runs attacker-controlled Python inside a three-layer sandbox that can be fully bypassed by passing a str subclass with an overridden startswith() method to the _safe_getattr wrapper, achieving arbitrary OS command execution on the host. This issue has been patched in version 1.5.90.
CVE-2026-25632CVSS 10EPyT-Flow is a Python package designed for the easy generation of hydraulic and water quality scenario data of water distribution networks. Prior to 0.16.1, EPyT-Flow’s REST API parses attacker-controlled JSON request bodies using a custom deserializer (my_load_from_json) that supports a type field. When type is present, the deserializer dynamically imports an attacker-specified module/class and instantiates it with attacker-supplied arguments. This allows invoking dangerous classes such as subprocess.Popen, which can lead to OS command execution during JSON parsing. This also affects the loading of JSON files. This vulnerability is fixed in 0.16.1.
CVE-2026-28505CVSS 10Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Prior to version 2.17.0, the str_eval() function in notification_handler.py implements a sandboxed eval() for notification text templates. The sandbox attempts to restrict callable names by inspecting code.co_names of the compiled code object. However, co_names only contains names from the outer code object. When a lambda expression is used, it creates a nested code object whose attribute accesses are stored in code.co_consts, NOT in code.co_names. The sandbox never inspects nested code objects. This issue has been patched in version 2.17.0.
CVE-2025-54381CVSS 9.9BentoML is a Python library for building online serving systems optimized for AI apps and model inference. In versions 1.4.0 until 1.4.19, the file upload processing system contains an SSRF vulnerability that allows unauthenticated remote attackers to force the server to make arbitrary HTTP requests. The vulnerability stems from the multipart form data and JSON request handlers, which automatically download files from user-provided URLs without validating whether those URLs point to internal network addresses, cloud metadata endpoints, or other restricted resources. The documentation explicitly promotes this URL-based file upload feature, making it an intended design that exposes all deployed services to SSRF attacks by default. Version 1.4.19 contains a patch for the issue.
