Details

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.
