CVE-2026-101954 is unauthenticated root-level takeover when J-Web HTTP/HTTPS is reachable. Hunt for Junos devices with web-management enabled on untrusted interfaces, unexpected successful unauthenticated hits to J-Web paths, and post-advisory config changes that add admin users or NETCONF sessions. Pair with MX Series logs for anomalous IKE certificate-based exchanges (CVE-2026-102182) and SRX Security Intelligence feed-fetch anomalies (CVE-2026-102062). Vendor states no known malicious exploitation yet — treat as priority exposure reduction.
