Answer in brief
CVE-2026-57028 records a High severity (CVSS 7.3) vulnerability in Junos OS Evolved: A port which has been inadvertently exposed can be reached by an attacker. The current sources do not mark it as known exploited. The current feed maps Juniper Networks/Junos OS Evolved (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
