Juniper Networks Patches Dozens of Junos OS Vulnerabilities

Juniper Networks released patches for nearly three dozen vulnerabilities in Junos OS, Junos OS Evolved, vLWC, CTP OS, and Apstra that could enable privilege escalation, denial-of-service, or remote command execution. The most severe is CVE-2026-33784, a default high-privileged account password in the Support Insights vLWC, and Juniper says it is not aware of any active exploitation of these flaws. #JuniperNetworks #JunosOS
