What is CVE-2025-47274?

ToolHive, a utility for managing Model Context Protocol (MCP) servers, contains a vulnerability where secrets are unintentionally written to run configuration files during the startup process of MCP server containers. This flaw affects versions before 0.0.33. An attacker with access to the user's home directory can read these secrets without direct access to the secure secrets store. This issue only affects secrets associated with containers that have existing run configurations at any given time. Version 0.0.33 addresses this flaw, and users are advised to stop any running MCP servers and delete existing configurations to mitigate risk.
