CVE-2026-57028

Description

An Improper Restriction of Communication Channel to Intended Endpoints vulnerability in Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause license exhaustion.

Due to an incorrect initialization, a process which should only be able to communicate internally within the device, can be reached over the network via an open port. This leads to unauthorized access to the license management.

This issue affects all Junos OS Evolved versions before 23.2R2-EVO.
