Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Obot versions before 0.23.0 do not enforce authentication on the MCP Registry endpoints under /v0.1 when registry authentication is enabled, so unauthenticated callers can list catalog server metadata such as names, descriptions, repository URLs and connect URLs. Exposed data does not include credential values, and connecting to the servers still requires authentication. Upgrade the Obot package to version 0.23.0 or later.
