CVE-2024-4343·Python vulnerability

A Python command injection vulnerability exists in the `SagemakerLLM` class's `complete()` method within `./private_gpt/components/llm/custom/sagemaker.py` of the imartinez/privategpt application, versions up to and including 0.3.0. The vulnerability arises due to the use of the `eval()` function to parse a string received from a remote AWS SageMaker LLM endpoint into a dictionary. This method of parsing is unsafe as it can execute arbitrary Python code contained within the response. An attacker can exploit this vulnerability by manipulating the response from the AWS SageMaker LLM endpoint to include malicious Python code, leading to potential execution of arbitrary commands on the system hosting the application. The issue is fixed in version 0.6.0.

How to fix this CVE

Upgrade the privategpt application to version 0.6.0 or later, which replaces the unsafe eval() function with secure JSON parsing in the SagemakerLLM component. If you are using privategpt through a Python package manager, update immediately and restart any services using the library. For systems running older versions, isolate AWS SageMaker endpoint communications through network segmentation until the patch can be applied.

sudo dnf update python3 && pip3 install --upgrade privategpt

Defensia detects this vulnerability

How to check if you are affected

  1. Check the installed privategpt version with: pip3 show privategpt | grep Version
  2. Verify the SagemakerLLM component is in use by searching your application configuration: grep -r 'SagemakerLLM' /path/to/privategpt/config/
  3. Search application logs for unusual Python code execution patterns: grep -i 'eval\|exec\|__import__' /var/log/application.log | grep -i sagemaker
  4. Confirm the patch was applied by checking the component file: grep -n 'json.loads\|ast.literal_eval' /path/to/privategpt/components/llm/custom/sagemaker.py

FAQ

What is CVE-2024-4343?

CVE-2024-4343 is a critical command injection vulnerability in privategpt's SagemakerLLM class that uses unsafe eval() to parse responses from AWS SageMaker endpoints, allowing attackers to execute arbitrary Python code by tampering with endpoint responses.

Is CVE-2024-4343 being actively exploited?

No, according to CISA's Known Exploited Vulnerabilities (KEV) catalog, CVE-2024-4343 is not currently being actively exploited in the wild, and no public exploits are available.

What versions of privategpt are affected by CVE-2024-4343?

All versions of privategpt up to and including 0.3.0 are affected; the vulnerability is fixed in version 0.6.0 and later.

How do I check if my server is vulnerable to CVE-2024-4343?

Run 'pip3 show privategpt' and verify the version is 0.6.0 or higher. If the version is 0.3.0 or earlier and your application uses SagemakerLLM, your system is vulnerable.

Does Defensia detect CVE-2024-4343?

Yes — Defensia's CVE advisory scanner compares installed Python package versions against the NVD database. If privategpt is installed on a monitored server, CVE-2024-4343 will appear in your dashboard with remediation steps.

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-2026-28505CVSS 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-2026-32871CVSS 10FastMCP is a Pythonic way to build MCP servers and clients. Prior to version 3.2.0, the OpenAPIProvider in FastMCP exposes internal APIs to MCP clients by parsing OpenAPI specifications. The RequestDirector class is responsible for constructing HTTP requests to the backend service. A vulnerability exists in the _build_url() method. When an OpenAPI operation defines path parameters (e.g., /api/v1/users/{user_id}), the system directly substitutes parameter values into the URL template string without URL-encoding. Subsequently, urllib.parse.urljoin() resolves the final URL. Since urljoin() interprets ../ sequences as directory traversal, an attacker controlling a path parameter can perform path traversal attacks to escape the intended API prefix and access arbitrary backend endpoints. This results in authenticated SSRF, as requests are sent with the authorization headers configured in the MCP provider. This issue has been patched in version 3.2.0.
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-2026-25632CVSS 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.
