CVE-2024-45847·Python vulnerability

An arbitrary code execution vulnerability exists in versions 23.11.4.2 up to 24.7.4.1 of the MindsDB platform, when one of several integrations is installed on the server. If a specially crafted ‘UPDATE’ query containing Python code is run against a database created with the specified integration engine, 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 to eliminate the arbitrary code execution risk introduced by unsafe eval() usage in UPDATE query handling. Organizations running MindsDB versions 23.11.4.2 through 24.7.4.0 with active database integrations should prioritize this patch, as the vulnerability allows authenticated users to execute arbitrary Python code on the server through specially crafted SQL queries.

sudo dnf update python3 -y

WAF mitigation (if patching is not yet possible)

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

Block or rate-limit UPDATE queries containing suspicious Python keywords (import, exec, eval, __import__, subprocess, os.system) in the request body or parameters. Implement query whitelisting to permit only expected UPDATE patterns against MindsDB databases.

How to check if you are affected

  1. Run `python3 --version` and `pip3 list | grep -i mindsdb` to confirm MindsDB installation and version
  2. Check MindsDB config file (typically ~/.mindsdb/config.json or /etc/mindsdb/config.json) to identify which database integrations are enabled
  3. Search application logs for UPDATE queries containing Python syntax like 'import', 'exec(', 'eval(', '__import__', or 'subprocess' in the query payload
  4. Verify the fix by re-running `pip3 show mindsdb` and confirming the version is 24.7.4.1 or higher

FAQ

What is CVE-2024-45847?

CVE-2024-45847 is a critical remote code execution flaw in MindsDB that allows authenticated database users to inject and execute arbitrary Python code through malformed UPDATE statements. The vulnerability stems from the platform passing unsanitized user input directly to Python's eval() function without proper validation.

Is CVE-2024-45847 being actively exploited?

As of the latest advisory, CVE-2024-45847 is not listed on the CISA Known Exploited Vulnerabilities catalog, and no public exploit code has been released. However, the vulnerability requires only low privileges and straightforward attack mechanics, making it likely to be weaponized.

What versions of MindsDB are affected by CVE-2024-45847?

MindsDB versions 23.11.4.2 through 24.7.4.0 are vulnerable. Version 24.7.4.1 and all subsequent releases include the remediation.

How do I check if my server is vulnerable to CVE-2024-45847?

Run `pip3 show mindsdb | grep Version` and compare against the vulnerable range (23.11.4.2 to 24.7.4.0). If your version falls within this range and you have database integrations enabled, your deployment is at risk.

Does Defensia detect CVE-2024-45847?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If MindsDB is installed on a monitored server, CVE-2024-45847 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.
