Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability was detected in universal-tool-calling-protocol python-utcp 1.1.0. This affects an unknown function of the component utcp-gql/utcp-websocket. Performing a manipulation results in server-side request forgery. The attack can be initiated remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A server-side request forgery (SSRF) vulnerability exists in the utcp-gql/utcp-websocket component of python-utcp version 1.1.0. The vulnerability allows remote attackers to make the server perform arbitrary requests to internal or external resources by manipulating input to the websocket/GraphQL endpoint.

MitigationImplement strict allowlist-based URL validation for all outgoing requests and restrict network connectivity to trusted endpoints only.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if python-utcp is installed
    Run 'pip show python-utcp' or check your package manager to retrieve the installed version of the python-utcp package
    Affected if The installed version is 1.1.0 (the affected version)
  2. Determine if utcp-gql component is in use
    Inspect your running services or application configuration to check if the GraphQL endpoint (utcp-gql) is enabled or deployed
    Affected if The utcp-gql component is running and accepts external input
  3. Determine if utcp-websocket component is in use
    Inspect your running services or application configuration to check if the WebSocket endpoint (utcp-websocket) is enabled or deployed
    Affected if The utcp-websocket component is running and accepts external input
  4. Inspect URL/endpoint parameter handling
    Review the source code or configuration of the utcp-gql and utcp-websocket components to identify where URL or endpoint parameters are processed
    Affected if The components accept user-controlled URL or endpoint parameters without strict allowlist validation

A user is affected if python-utcp version 1.1.0 is installed and either the utcp-gql or utcp-websocket component is running with exposed URL/endpoint parameters that lack allowlist-based input validation.
