CyberRota Analysis

AI-Generated

The vulnerability in Cosmos allows unauthorized disclosure of Constellation device metadata when a requester sends any non-empty Authorization header, as the system fails to validate the token before processing. This could lead to exposure of sensitive information about connected devices, potentially compromising user privacy and security. Users running version 0.22.18 should prioritize upgrading to version 0.22.19 to mitigate this risk.

Original NVD Description

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.
