Cosmos provides users the ability self-host a home server by acting as a secure gateway to your application, as well as a server manager. In 0.22.18, `GET /cosmos/api/constellation/public-devices` discloses Constellation device metadata to a requester that supplies any non-empty Authorization header. The handler strips the string Bearer from the header but never validates the resulting token and never uses it in the database query. This vulnerability is fixed in 0.22.19.
