CVE-2026-49447: CWE-287: Improper Authentication in azukaar Cosmos-Server
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.
AI Analysis
Technical Summary
The vulnerability in azukaar Cosmos-Server 0.22.18 involves the GET /cosmos/api/constellation/public-devices endpoint improperly handling authentication.

Consequently, unauthorized users can retrieve Constellation device metadata. This is classified as CWE-287: Improper Authentication. The flaw is resolved in version 0.22.19.
Potential Impact
An attacker can access Constellation device metadata without proper authentication by supplying any non-empty Authorization header. The confidentiality of device metadata is compromised, but there is no impact on integrity or availability. The CVSS score is 5.3 (medium severity), reflecting network attack vector, no privileges required, no user interaction, and limited confidentiality impact.
Mitigation Recommendations
Upgrade to azukaar Cosmos-Server version 0.22.19 or later, where this vulnerability is fixed. Since the vendor advisory indicates the issue is resolved in 0.22.19, applying this official fix is the recommended mitigation. Patch status is confirmed by the vendor's versioning information.
