CVE-2026-18965Network attack vector

Network-wide device disclosure via unauthorized endpoints

Published Aug 27, 2026 · Updated Aug 27, 2026

Missing authorization in management endpoints in all versions of PayRange API allows remote attackers to read details for every network device. The endpoints return verbose device records without enforcing an authorization decision for either an account holder or an anonymous requester. Remote reachability is sufficient, with or without an account; CISA does not identify the individual fields exposed in each record.
