What it is

Obot versions before v0.23.0 fail to enforce authentication on MCP Registry endpoints under /v0.1/* when registry authentication is enabled. Unauthenticated attackers can read registry metadata including server names, descriptions, repository URLs, and connect URLs by sending GET requests to /v0.1/servers.
