Improper Authentication
CVE-2025-30215
Summary
NATS-Server is a high-performance server for NATS.io, the cloud and edge native messaging system. In NATS-Server, the management of "JetStream" assets happens with messages in the "$JS.subject" namespace in the system account; this is partially exposed to regular accounts to allow account holders to manage their assets. Some of the JS API requests were missing access controls, allowing any user with JS management permissions on any account to perform certain administrative actions on any JS asset on any other account. At least one of the unprotected APIs allows for data destruction. None of the affected APIs allow disclosing stream contents. This vulnerability affects github.com/nats-io/nats-server package versions 2.2.0 through 2.10.27-binary, and 2.11.0-RC.1 through 2.11.1-binary.

CWE-287 - Improper Authentication
Improper (or broken) authentication attacks are widespread, and have accounted for many of the worst data breaches in recent years. Improper authentication attacks are a class of vulnerabilities where an attacker impersonates a legitimate user by exploiting weaknesses in either session management or credential management to gain access to the user’s account. This can result in disclosure of sensitive information, and can lead to system compromise, theft, identity theft, and fraud.
