CVE-2025-46725·Python vulnerability

Langroid is a Python framework to build large language model (LLM)-powered applications. Prior to version 0.53.15, `LanceDocChatAgent` uses pandas eval() through `compute_from_docs()`. As a result, an attacker may be able to make the agent run malicious commands through `QueryPlan.dataframe_calc]`) compromising the host system. Langroid 0.53.15 sanitizes input to the affected function by default to tackle the most common attack vectors, and added several warnings about the risky behavior in the project documentation.

How to fix this CVE

Update the Langroid framework to version 0.53.15 or later to patch the unsafe pandas eval() execution vulnerability in LanceDocChatAgent. This version implements input sanitization to prevent malicious code injection through the QueryPlan.dataframe_calc parameter. Review your application's use of compute_from_docs() and consider implementing additional input validation layers beyond the default sanitization.

sudo dnf update python3-langroid || pip3 install --upgrade langroid>=0.53.15

Defensia detects this vulnerability

How to check if you are affected

  1. Check installed Langroid version: pip3 show langroid | grep Version
  2. Verify if LanceDocChatAgent is instantiated in your codebase: grep -r 'LanceDocChatAgent' /path/to/your/app
  3. Search application logs for compute_from_docs() calls with unexpected parameters: grep -i 'compute_from_docs\|dataframe_calc' /var/log/app.log
  4. After patching, confirm version: pip3 show langroid | grep Version should show 0.53.15 or higher

FAQ

What is CVE-2025-46725?

CVE-2025-46725 is a critical remote code execution vulnerability in Langroid's LanceDocChatAgent that exposes unsafe pandas eval() functionality, allowing attackers to execute arbitrary system commands through malicious dataframe calculation parameters.

Is CVE-2025-46725 being actively exploited?

No, CVE-2025-46725 is not listed in the CISA Known Exploited Vulnerabilities catalog and no public exploits have been disclosed, but the critical CVSS 9.8 score warrants immediate patching.

What versions of Python are affected by CVE-2025-46725?

This vulnerability affects Langroid versions prior to 0.53.15 running on any Python 3.x installation. The issue resides in the Langroid framework, not Python itself.

How do I check if my server is vulnerable to CVE-2025-46725?

Run 'pip3 show langroid' and check if the Version is below 0.53.15. If Langroid is not installed or your version is 0.53.15+, you are not vulnerable.

Does Defensia detect CVE-2025-46725?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Langroid is installed on a monitored server, CVE-2025-46725 will appear in your dashboard with remediation steps.

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-2026-33054CVSS 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.
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-2026-8481CVSS 9.9IBM Langflow OSS 1.0.0 through 1.10.0 contain a critical remote code execution vulnerability in the code validation API endpoint. The POST /api/v1/validate/code endpoint accepts user-supplied Python code and executes it directly using Python's built-in exec() function without sandboxing, input validation, or privilege restrictions, enabling any authenticated user to execute arbitrary system commands with the full privileges of the Langflow server process.
