CVE-2026-38716·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 application export function. This vulnerability allows remote attackers to execute arbitrary commands as root via a crafted input.

How to fix this CVE

Update Python to version 1.0.0.r20044 or later to patch a critical command injection flaw in the application export function. Organizations running InHand Networks IR912 or IR915 devices with vulnerable Python versions should prioritize this update immediately, as the vulnerability allows unauthenticated remote attackers to execute arbitrary commands with root privileges. Verify the patch is applied and test the export functionality in a staging environment before deploying to production.

sudo dnf update python3

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

POST.*export.*[;&|`$()\{\}]|export.*cmd=.*[;`|]|application.*export.*bash|sh.*-c.*export

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 requests to export endpoints containing shell metacharacters (;, |, &, `, $, (), {}). Implement strict input validation on the export function to reject payloads containing command delimiters and enforce a whitelist of allowed parameter values.

How to check if you are affected

  1. Step 1: Run `python3 --version` to check the installed Python version and compare against 1.0.0.r20044
  2. Step 2: Identify if the export function is exposed via web interface by checking `netstat -tlnp | grep python` and reviewing listening ports and associated services
  3. Step 3: Search application logs for suspicious export requests with unusual parameters: `grep -i 'export\|cmd\|;\|`' /var/log/application.log | head -100`
  4. Step 4: Verify the patch by running `python3 --version` again and confirming the version is 1.0.0.r20044 or higher

FAQ

What is CVE-2026-38716?

CVE-2026-38716 is a critical command injection vulnerability in the Python export function that allows remote attackers to bypass authentication and execute arbitrary OS commands with root-level privileges on InHand IR912 and IR915 devices.

Is CVE-2026-38716 being actively exploited?

According to CISA data, this vulnerability is not currently listed in the Known Exploited Vulnerabilities (KEV) catalog, and no public exploits are publicly available. However, the critical CVSS score (9.8) warrants immediate patching as a matter of principle.

What versions of Python are affected by CVE-2026-38716?

All versions of Python up to and including 1.0.0.r20044 are affected. The vulnerability has been patched in version 1.0.0.r20044 and later.

How do I check if my server is vulnerable to CVE-2026-38716?

Run `python3 --version` and compare the output to 1.0.0.r20044; if your version is earlier, your system is vulnerable. Additionally, check for the presence of the export function in your running processes with `ps aux | grep python`.

Does Defensia detect CVE-2026-38716?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Python is installed on a monitored server, CVE-2026-38716 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.
