CVE-2025-53365 – Apache MCP Python SDK Denial of Service

CVE ID : CVE-2025-53365

Published : July 4, 2025, 10:15 p.m. | 44 minutes ago

Description : The MCP Python SDK, called `mcp` on PyPI, is a Python implementation of the Model Context Protocol (MCP). Prior to version 1.10.0, if a client deliberately triggers an exception after establishing a streamable HTTP session, this can lead to an uncaught ClosedResourceError on the server side, causing the server to crash and requiring a restart to restore service. Impact may vary depending on the deployment conditions, and presence of infrastructure-level resilience measures. Version 1.10.0 contains a patch for the issue.

Severity: 0.0 | NA
