Описание
FastMCP is the standard framework for building MCP applications. Prior to version 2.14.2, the server does not properly respect the resource parameter submitted by the client in the authorization and token request. Instead of issuing the token explicitly for the MCP server, the token is issued for the base_url passed to the OAuthProxy during initialization. This issue has been patched 2.14.2.
A flaw was found in FastMCP, a framework for building MCP applications. The server does not correctly process the resource parameter provided by the client during authorization and token requests. This can lead to security tokens being issued for an unintended base URL (Uniform Resource Locator) instead of the specific MCP server. Such improper token issuance could allow an attacker to gain unauthorized access or disclose sensitive information.
Отчет
Important: FastMCP, as utilized in several Red Hat products, contains a flaw where the server incorrectly processes the resource parameter during authorization and token requests. This can lead to security tokens being issued for an unintended base URL, potentially allowing unauthorized access or information disclosure. This affects Hosted OpenShift Clusters, Red Hat OpenShift AI, and Red Hat Satellite. Red Hat Developer Hub is not affected as the vulnerable code is not present.
