CVE-2026-35002·Python vulnerability

Agno versions prior to 2.3.24 contain an arbitrary code execution vulnerability in the model execution component that allows attackers to execute arbitrary Python code by manipulating the field_type parameter passed to eval(). Attackers can influence the field_type value in a FunctionCall to achieve remote code execution.

How to fix this CVE

Update Python and the Agno package to version 2.3.24 or later to patch the eval() injection vulnerability in the model execution component. This fix eliminates the ability for attackers to manipulate the field_type parameter and execute arbitrary code through FunctionCall objects. Verify the update is applied and restart all Python-based services that depend on Agno.

sudo dnf update python3 && pip install --upgrade agno>=2.3.24

Defensia detects this vulnerability

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

POST requests to Agno endpoints with crafted FunctionCall payloads containing shell metacharacters or Python code in the field_type parameter; example: field_type=__import__('os').system('command') or field_type=eval(...)

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 sanitize FunctionCall requests where field_type parameter contains: eval, exec, __import__, os.system, subprocess, or shell metacharacters (|, ;, &, $, backticks). Implement strict whitelist validation for field_type values at the API gateway level.

How to check if you are affected

  1. Check Agno version: pip show agno | grep Version
  2. Identify exposed Agno instances: grep -r 'from agno' /opt /home /srv --include='*.py' 2>/dev/null
  3. Search application logs for eval() calls with user-controlled field_type: grep -i 'field_type\|FunctionCall' /var/log/application* /var/log/python* 2>/dev/null
  4. Verify patch applied: pip show agno | grep 'Version: 2.3.24' && echo 'Patched' || echo 'Vulnerable'

FAQ

What is CVE-2026-35002?

CVE-2026-35002 is a critical remote code execution vulnerability in Agno's model execution component where the field_type parameter is passed unsafely to Python's eval() function, allowing attackers to execute arbitrary code without authentication.

Is CVE-2026-35002 being actively exploited?

No, CVE-2026-35002 is not currently listed on CISA's Known Exploited Vulnerabilities catalog, and no public exploits have been released. However, the low barrier to exploitation makes prompt patching essential.

What versions of Python are affected by CVE-2026-35002?

All versions of Agno prior to 2.3.24 are vulnerable. The vulnerability exists in the model execution component across all affected Agno releases up to and including 2.3.23.

How do I check if my server is vulnerable to CVE-2026-35002?

Run 'pip show agno' and verify the version is 2.3.24 or later. If the version is 2.3.23 or earlier, your system is vulnerable and requires immediate patching.

Does Defensia detect CVE-2026-35002?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If Agno is installed on a monitored server, CVE-2026-35002 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.
