NVD Description

Note: Versions mentioned in the description apply only to the upstream nats package and not the nats package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

NATS nats-server before 2.9.23 and 2.10.x before 2.10.2 has an authentication bypass. An implicit $G user in an authorization block can sometimes be used for unauthenticated access, even when the intention of the configuration was for each user to have an account. The earliest affected version is 2.2.0.
