CVE-2025-47274 (opens in a new tab)How to fix?
Upgrade github.com/stacklok/toolhive/pkg/secrets to version 0.0.33 or higher.
Overview
Affected versions of this package are vulnerable to Missing Encryption of Sensitive Data due to the ordering of code used to start an MCP server container. An attacker can read secrets without needing access to the secrets store itself by gaining access to the home folder of the user who starts the MCP server. This is only exploitable if secrets were used in containers whose run configs exist at a point in time - other secrets remaining inaccessible.
Workaround
This vulnerability can be mitigated by stopping and deleting any running MCP servers, or manually removing any runconfigs from $HOME/Library/Application Support/toolhive/runconfigs/ (macOS) or $HOME/.state/toolhive/runconfigs/ (Linux).
