CISA Gives UniFi OS and Lantronix Flaws a June 26 Patch Deadline
CISA added three Ubiquiti UniFi OS flaws and a Lantronix EDS5000 code-injection bug to its Known Exploited Vulnerabilities catalog, setting a June 26 remediation deadline for federal agencies. The risk is not just another CVE list: exposed network management interfaces can become a fast path to device control.
CISA’s June 23 Deadline Puts Cisco SD-WAN, Chrome, and Arista EOS on the Triage List
CISA’s June 23 remediation deadline covers three actively exploited flaws across Cisco Catalyst SD-WAN Manager, Google Chrome’s V8 engine, and Arista EOS. The useful move for security teams is not treating them as one patch chore, but triaging each layer: network control plane, browsers, and tunnel decapsulation paths.
CISA Puts FortiSandbox Exploits on an Emergency Patch Clock
CISA added two Fortinet FortiSandbox command-injection flaws to its exploited-vulnerabilities catalog on July 16, giving federal agencies until July 19 to remediate. Security teams should patch affected FortiSandbox systems, restrict management access, and review logs and connected credentials if exposure existed before the upgrade.
AryStinger Botnet Turns Old Routers Into Attack Proxies
Security researchers say AryStinger has compromised more than 4,300 legacy routers, turning aging home and small-office gear into proxy and reconnaissance infrastructure. The campaign is a reminder that end-of-life routers are not just slow or outdated; they can become someone else’s attack platform.
Cisco ISE Flaws Put Network Access Control on a Patch Clock
Cisco patched two Identity Services Engine flaws that can expose hashed credentials and let an authenticated attacker run commands on the underlying operating system. The urgency is highest for teams running ISE 3.4, ISE 3.5, or ISE-PIC, especially because one Cisco ISE 3.5 fix is not due in the normal patch stream until August.
F5’s Emergency NGINX Patches Put Web Server Teams on a Fast Upgrade Clock
F5 issued out-of-band NGINX updates for flaws affecting HTTP/3, proxy protocol, gRPC, Gateway Fabric, and related products. Teams running internet-facing NGINX should check versions, exposed modules, Kubernetes ingress paths, and temporary mitigations before treating this as routine patching.
HPE Turns Juniper Into the Network Layer for AI Factories
HPE used Discover 2026 to fold Juniper deeper into its AI data center strategy, adding QFX switches for inference and AMD Helios, Mist and Marvis AIOps updates, and SASE controls for self-driving networks.
