CVE-2025-66454 is a medium severity vulnerability in ArcadeAI's arcade-mcp HTTP server versions prior to 1.5.4. The server uses a hardcoded default worker secret key "dev" that is never validated or overridden during startup. This allows unauthenticated attackers who know the default key to forge valid JWT tokens, bypassing FastAPI authentication entirely. Exploitation grants remote access to all worker endpoints, including tool enumeration and invocation, without any credentials. The vulnerability does not require user interaction or privileges and is exploitable over the network. It is fixed in version 1.5.4.
