Name of the Vulnerable Software and Affected Versions NATS Server versions prior to 2.2.0

Description The issue is caused by an integer overflow that allows a remote attacker to crash the server by sending a crafted request. If authentication is enabled, the attacker must first authenticate. This can be exploited by sending a specifically crafted request to the server.

Recommendations For versions prior to 2.2.0, update to version 2.2.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the server to minimize the risk of exploitation.
