Cosmos-Server's constellation public-devices endpoint accepts arbitrary bearer tokens

Summary 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...
