How to Fix CVE-2022-29946

To remediate this vulnerability, upgrade all affected Github.com/nats io/nats server/v2 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/nats-io/nats-server/v2 fixed: 2.8.2 
Upgrade github.com/nats-io/nats-server/v2 to 2.8.2
github.com/nats-io/nats-streaming-server fixed: 0.24.6 
Upgrade github.com/nats-io/nats-streaming-server to 0.24.6
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/nats-io/nats-server/v2

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-29946, inspect your project dependencies for Github.com/nats io/nats server/v2:

inspect dependencies for github.com/nats-io/nats-server/v2

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. In Github.com/nats io/nats server/v2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

NATS.io NATS Server before 2.8.2 and Streaming Server before 0.24.6 could allow a remote attacker to bypass security restrictions, caused by the failure to enforce negative user permissions in one scenario. By using a queue subscription on the wildcard, an attacker could exploit this vulnerability to allow denied subjects.
