- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
CERT-FR published an advisory relaying Juniper Networks' security bulletin JSA112183, describing multiple vulnerabilities discovered internally by Juniper in its Session Smart Router and Session Smart Conductor products. The flaws collectively allow an attacker to compromise data integrity and confidentiality, bypass security policies, cause remote denial of service, execute arbitrary code remotely, and escalate privileges. No evidence of active exploitation in the wild is mentioned in the advisory.
Affected versions are Session Smart Conductor and Session Smart Router releases prior to 7.0.5, 7.1.7, and 7.2.3. Eighteen CVEs were assigned to this batch of issues (CVE-2026-103390 through CVE-2026-103394, CVE-2026-103400 through CVE-2026-103411, and CVE-2026-106079). Juniper has released fixed versions and CERT-FR directs administrators to the vendor bulletin for patch acquisition. Defenders operating Session Smart Router/Conductor deployments should prioritize upgrading to the fixed releases given the breadth of impact (RCE, privilege escalation, DoS) across network edge/SD-WAN infrastructure.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
