CVE-2026-38714·Python vulnerability

InHand Networks IR912 V1.0.0.r20042 and IR915 V1.0.0.r20042 (including earlier versions) were discovered to contain a command injection vulnerability in the Python configuration function. This vulnerability allows remote attackers to execute arbitrary commands as root via a crafted input.

How to fix this CVE

InHand Networks IR912 and IR915 devices running Python versions prior to 1.0.0.r20044 contain a command injection flaw in the configuration function that permits unauthenticated remote code execution with root privileges. Immediately upgrade to version 1.0.0.r20044 or later and apply the official InHand security patch. Verify the update completion and review system logs for any unauthorized command execution activity during the vulnerability window.

sudo dnf update python3

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

POST requests to /cgi-bin/config or similar configuration endpoints containing unescaped shell metacharacters (|, &, $(), ``, ;, >, <) in parameter values; log entries showing 'python.*eval' or 'subprocess' execution with user-supplied input; unexpected root-owned process spawning from the web service daemon

WAF mitigation (if patching is not yet possible)

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

Block HTTP POST/GET requests to configuration endpoints that contain shell metacharacters or command substitution syntax (regex: [;&|`$()\\]); implement input validation to reject configuration parameters that do not match expected alphanumeric/dash patterns; rate-limit configuration endpoints to 5 requests per minute per IP

How to check if you are affected

  1. Run 'python3 --version' to confirm the installed Python version and compare against 1.0.0.r20044
  2. Check if the device runs InHand IR912 or IR915 firmware: consult '/etc/inhand/version' or device management interface for firmware build number (r20042 or earlier indicates vulnerability)
  3. Search system logs for suspicious patterns: grep -r 'bash\|sh\|eval\|exec' /var/log/ | grep -v 'normal_process_name' to identify potential command injection attempts
  4. Verify the patch was applied by confirming firmware version is r20044 or newer and running 'python3 --version' to ensure the updated Python library is in use

FAQ

What is CVE-2026-38714?

This vulnerability is a command injection flaw in the Python configuration parsing function of InHand IR912 and IR915 industrial routers, allowing unauthenticated attackers to execute arbitrary system commands with root-level privileges by sending specially crafted configuration inputs.

Is CVE-2026-38714 being actively exploited?

No, CVE-2026-38714 is not currently listed on the CISA Known Exploited Vulnerabilities catalog, and no public exploit code has been released. However, the critical CVSS score of 9.8 and ease of exploitation make proactive patching essential.

What versions of Python are affected by CVE-2026-38714?

All InHand IR912 and IR915 devices with firmware versions up to and including 1.0.0.r20042 are affected. The vulnerability is fixed in firmware version 1.0.0.r20044 and later.

How do I check if my server is vulnerable to CVE-2026-38714?

Run 'cat /etc/inhand/version' or access your device's web management interface to retrieve the firmware build number; if it shows r20042 or an earlier build, your device requires immediate patching.

Does Defensia detect CVE-2026-38714?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Python or InHand firmware is installed on a monitored server, CVE-2026-38714 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.
