CVE-2025-2945·Python vulnerability

Remote Code Execution security vulnerability in pgAdmin 4 (Query Tool and Cloud Deployment modules). The vulnerability is associated with the 2 POST endpoints; /sqleditor/query_tool/download, where the query_commited parameter and /cloud/deploy endpoint, where the high_availability parameter is unsafely passed to the Python eval() function, allowing arbitrary code execution. This issue affects pgAdmin 4: before 9.2.

How to fix this CVE

Upgrade pgAdmin 4 to version 9.2 or later, which removes unsafe eval() calls from the query tool and cloud deployment modules. This vulnerability allows authenticated attackers to execute arbitrary Python code through two specific POST endpoints. Immediately patch all pgAdmin 4 instances running versions prior to 9.2 in your environment.

sudo dnf update pgadmin4 && sudo systemctl restart pgadmin4

What an exploitation attempt looks like

Sample log line indicative of exploitation attempts:

POST /sqleditor/query_tool/download HTTP/1.1.*query_committed=.*(__import__|eval|exec|compile|os\.|sys\.|subprocess) or POST /cloud/deploy HTTP/1.1.*high_availability=.*(__import__|eval|exec|compile|os\.|sys\.|subprocess)

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 require authentication for POST requests to /sqleditor/query_tool/download and /cloud/deploy. Implement input validation to reject any query_committed or high_availability parameters containing Python built-in function names (eval, exec, compile, __import__, etc.) or module imports (os, sys, subprocess, socket). Use ModSecurity rules to detect eval() payloads.

How to check if you are affected

  1. Check pgAdmin 4 version: grep -r 'version' /pgadmin4/config_distro.py | grep -i version or access the pgAdmin web UI and check Settings > About
  2. Verify exposed endpoints: curl -s http://localhost:5050/sqleditor/query_tool/download -X OPTIONS -v | grep Allow and curl -s http://localhost:5050/cloud/deploy -X OPTIONS -v | grep Allow
  3. Search web server logs for POST requests to /sqleditor/query_tool/download or /cloud/deploy with suspicious query_committed or high_availability parameters: grep -E '(query_tool/download|cloud/deploy)' /var/log/pgadmin4/pgadmin4.log | grep POST
  4. Confirm remediation by running: pgadmin4 --version and verify output shows 9.2 or later

FAQ

What is CVE-2025-2945?

CVE-2025-2945 is a critical remote code execution vulnerability in pgAdmin 4 that stems from unsafe use of Python's eval() function in the Query Tool and Cloud Deployment modules. Authenticated users can inject arbitrary Python code through POST parameters to achieve code execution on the pgAdmin server.

Is CVE-2025-2945 being actively exploited?

No, according to CISA's Known Exploited Vulnerabilities (KEV) catalog, there is currently no evidence of active exploitation in the wild. However, the critical CVSS 9.9 score and public issue disclosure warrant immediate patching.

What versions of pgAdmin 4 are affected by CVE-2025-2945?

All versions of pgAdmin 4 prior to version 9.2 are vulnerable. The vulnerability was patched in pgAdmin 4 version 9.2 and later.

How do I check if my server is vulnerable to CVE-2025-2945?

Run 'pgadmin4 --version' to retrieve your installed version. If the output is 9.1 or earlier, your installation is vulnerable. Additionally, check if the endpoints /sqleditor/query_tool/download and /cloud/deploy are accessible to authenticated users.

Does Defensia detect CVE-2025-2945?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If pgAdmin 4 is installed on a monitored server, CVE-2025-2945 will appear in your dashboard with remediation steps.

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-2026-34938CVSS 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-2026-32871CVSS 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-2026-28505CVSS 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-2026-25632CVSS 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.
